I have a tidbit to share that may serve to restore a wee bit of faith in humanity.
Yesterday, I had to pick up an item for VWife at the local Tar-zhee, and I got into an un-fight with a guy over a parking spot. We spotted it at the same time, and signalled for it at the same time too. He kept waving me in, and I was flashing head lights at him to take it. There was a distinct vibe of the Looney Tunes polite gophers (“After you” “No, after you”) going on.
I spotted a different spot about 4 cars away, and went for that one instead. 
So, just to destroy any good feelings from the un-fight, my next stop at Wally*World pretty much undid everything. They were elbow-to-asshole busy, and I’ll bet I spent a half hour in line to check out. The cashier was having trouble getting a gift card to work, causing the delay. When I got up to her to pay, some jackass about 3 carts back opened up with a lot of snide comments intended for everyone to hear.
“You need to open another register here!”
“Hey cashier, are you new or something?”
“Walmart, you have a problem with this line!”
Ad nauseum. :rolleyes:
The poor cashier was gritting her teeth and praying under her breath, “Help me lord, I don’t need this today.” After the jackass started in with the second iteration of “We have a problem here…” I said to the register babe, “The problem is that you’re a grandstanding asshole.”
She lost it, and had to stop ring up my stuff until she quit laughing. “I love it when the customers say what I’m thinking.”
I replied, “I love it when people think the way I do.”
