Because “I gotta pee” isn’t gross. To me, to several here, and likely to most of the population.
“I got diarrhea and gotta go splatter in the toilet” is gross, “I gotta drain the lizard” is less gross, but still not probably acceptable. “I gotta pee” is something a kid would say and is no way gross, else prudes like you wouldn’t let them say it.
“I gotta drop a deuce or we’re gonna need a clean up on register 3!”
I never said that “I gotta pee” is gross. It’s just uncouth. It’s not polished or smooth, especially when emphasized three times in a row. The fact that it’s what kids say is EXACTLY the OP’s point. He wasn’t in a kindegartern. He was in a place of business.
Now is it a Pit-worthy complaint? No. The OP was right when he said his was a whiny rant. But some of the responses here are equally stupid, including yours. You’re acting like it’s so outrageous to expect an adult to excuse themselves like a fucking adult.
Goddamn, you’re one hard headed clueless fuck. Nobody has complained about “I gotta pee” despite how trailer trash it is all by itself. The complaint is about SHOUTING IT, repeating it over and over, painting a picture of her nasty ass hovered over a cesspool, splashing urine on her thighs, sticking her nasty hand down there, and then coming back to handle your shit. Fuck, I hope you don’t work for the public.
Boo hoo, the poor customers had to be momentarily aware that other people urinate. This is the kind of thing that needs to be filed under “move on,” if any notice is taken at all.
Ahh poor liberal…
Actually the OP was complaining about it. I find it funny the champion of fighting against the term “white trash” uses “trailer trash” but whatever, the OP said they shouted, but I’ve been to many a family dollar, and the cash registers are always very close together, so I assumed it was a figure of speech.
And she only said it the second time because cashier #2 obviously didn’t hear her. So she couldn’t have been YELLING it, now could she, you stupid old fucker. She said it the third time because she had to report to her supervisor what she was doing because her supervisor asked.
Wah, wah wah, somebody shouted Pee in a store, how uncouth, bunch of fucking fuddy duddy old hoity toity pieces of shit. Boo fucking hoo, what is somebody of your obviously elevated position of society doing in a fucking family dollar anyway. Go blow your Idol Donald Trump and leave us “trailer trash” alone.
I’m also glad there wasn’t a line at her register.
…'Cause, y’know, you gotta mind your pees and queues.
Now that would offend me if a clerk were to shout it at me in the dollar store! I’d laugh later, though.
God will punish you for that. And soon.
I thought the OP was bothered by the use of “pee” as well. I thought that had the cashier shouted “I have to use the ladies” our OP would not have been PO’d. I have gotten used to “pee” being part of everyday vernacular. It took some getting used to, but I’m acclimated to it. Apparently, not everyone is.
Look how you make shit up. I’ve never fought against the term “white trash”. The OP didn’t say anything about a Family Dollar store. There’s no mention of how close together the cash registers are. There’s no indication that the other cashier couldn’t hear (“What?” may simply mean “what the fuck did you dare to say?”) I may be old, but I’m not stupid. My idol is not Donald Trump; it is Rob Mariano. And you are a blithering idiot who cannot read.
That would be me. Do you like it? If so, why do you feel compelled to refer to a fellow human as garbage, and base that judgment on a cursory examination? How’s the air up there?
Lib, great little parody upthread. Busted a gut, Kemo Sabe.
Man, now I’m sorry I posted this damn thing from the get-go.
A little clarification: the registers were diagonal to each other, each maybe 10 feet apart. Pee-girl wasn’t exactly screaming it, but she wasn’t mumbling sotto voce, either. She said it brightly and happily; she didn’t appear to be in any pain.
I have no problem with the word “pee” whatsoever, but there’s a time and a place for everything – that’s my beef.
Next time I start a Pit thread, I’m going to make sure it’s about something everyone hates, like rabid Hitler-loving, water-poisoning pederast polecats.
And Liberal, if your imagination seriously conjures vivid imagery like that when you hear the word “pee” in public, the problem is you. I’m not kidding – if you haven’t been engaging in hyperbole here, you may want to seek help for your undiagnosed OCD or whatever the hell would have to wrong with your brain to make that happen to you. Believe me, it’s not normal, and it doesn’t happen to everyone. Most of us can hear someone talk about peeing without being overwhelmed with intense imagery of every step of the process and sickened by the thought of making contact with the person thereafter.
As long as they don’t pee in public, I’m ok with them.
It’s not OCD. It’s melancholia. 
Cashier 2: “Hey! Can you cover my register? I gotta go feed my rabid Hitler-loving, water-poisoning pederast polecats some non-poisoned cat food!”
I wouldn’t entirely agree with that, if I go to a store that adverised lower prices, then I would expect less professionalism that at a store that advertised great service. Screaming at someone is agressive behaviour, but saying the word “pee” (which is not exactly a corporate boardroom word) is not aggressive or harmful, its just slightly unprofessional. And anyone who is going to be offended by harmless buy slightly unprofessional behavior on the part of cashiers should NOT be shopping at the dollar store, which in my experience are the most cost-cutting retail stores you can find, short of buying your socks from some guy on the side of the highway. This cashier, and the manager, may have understood the context and childishness of the word “pee”, but they also probably understand that a dollar store is not exactly a Nordstroms. Seriously, dollar stores don’t offer top-notch service, they offer bargains, if they ring up your purchase accurately and promptly then your experience was exactly as advertised.
Back when the dollar store craze was new, I once asked a worker, “how much is this?”. Of course, she said a dollar. I then asked, “and this?”. (at the time it was funny. honest) 
I must confess: I think this has been the most sensible posting in the whole thread, mine own included.
A friend of mine did that once when we were in the 8th grade or so. This being New York, there’s an 8 percent sales tax on everything. So the cashier replied that the item cost $1.08.
My friend dropped to his knees, raised his arms in the air and shouted “NOOOOOOOOOO!”
I think George Lucas must have been in the store at the time.
