Oh, I just had this problem.
One of my guilty pleasures is Taco Bell. I’ve been going to the exact same Taco Bell for lunch every Monday for roughly 4 years. (I call it Taco Bell Monday.) I order the same thing every time. I don’t eat meat either, and many times–usually when there’s someone new taking order–my order has come out with that atrocious ground beast in it.
Because I’ve had many problems trying to get my order correct, despite enunciating clearly, repeating myself, and asking the order-taker to repeat my order back to me to confirm, this does not prevent the people in the kitchen from not reading the board correctly and fucking up the order anyway. So I’ve got the correct sequence of requests down pat. Also, my sister and her husband have worked at Taco Bells for about thousands of years (my BIL is a Regional Manager), so they’ve instructed me on what the cashier’s board looks like, what keys they have to punch to get my order correct, and how to say the order so it comes out right.
Despite all that…
I cruise through the drive thru a couple weeks ago. Pull up to the little speaker and give my standard, practiced and proven order: “Burrito Supreme minus beef, one order of nachos and a medium diet.”
The drive thru guy proceeds to argue with me. “I put that in as a bean burrito supreme because you can’t get a beef burrito supreme without beef. Your order will come out wrong because we will have to substitute beans.” (Ss if that is rocket science and the morons in the kitchen will be unable to understand the word “substitute.”)
“Um, no, I’ve been ordering this same thing every week for a couple years now, and there is no such thing as a Beef Burrito Supreme on your menu. (I’m looking at the menu board as I say this – nope, no Beef Burrito Supreme) Burrito Supremes* all *come with both beans and beef so all you have to do is instruct the kitchen to leave off the beef.”
[Side rant: Why is it, when you add something to an order, you can get charged extra, like $0.25 for extra cheese on the Veggie burger at BK… but when you order something to be subtracted from your order, like “take off the beef,” you don’t get a 0.25 or .050 discount? That pisses me off. I have to pay extra for a burrito to be made properly because I’ve asked for the most expensive ingredient to be omitted? Life is hard for vegetarians.]
Anyway, this drive thru guy continues to argue with me about how to input the order, so I just said, “Fine, man, do whatever you’ve gotta do.” And thought, “Just don’t put fucking cow on my burrito because I will retch while I’m ripping you a new asshole in about a half hour.”
So I pick up my food, drive 20 minutes home, open the wrapper and it’s a goddamn Burrito Supreme with BOTH beans and fucking meat on it. I check the receipt and the order has been input properly. After all that, and they still fucked it up. Filled with Grrrr. So I call that shop, and after 20 rings, they still haven’t answered. I hang up and call again. This time, they finally pick up in about 15 rings. I ask for the manager. Whoever answered the phone didn’t bother to say, “Oh yeah, I’ll get her” or anything; I just heard the phone hit the table with a thunk. Finally the manager gets on and I tell her what happened, and ask her to make me another burrito, this time with no goddamn beef on it, and explain I’ll be there in 15 minutes to pick it up. When I got there, and she saw me, she never said a word to me, just turned to the burrito-maker-guys and told them to make me another burrito. I watched as my burrito was made correctly, and was handed off to me without a word. Not one employee spoke to me the entire time I stood there. This of course burned up my entire lunch hour, so I had to take the food back to work and eat at my desk.
The moral: It took me a long time to figure out how to order my burrito so your kitchen staff doesn’t fuck up the order. Don’t fucking argue with me about how to input the damn order. Why do I have to train all the new employees? Isn’t there a shift manager who has that responsibility?
ETA: Yes, I realize I said it took 20 minutes to get home but 15 minutes to get back to Taco Bell from my house. I had a headwind.
