Wut do? I had this happen the other night and I'm not sure if I overreacted. It's an older guy (looks like he's in his 50s) who works the graveyard shift that I now think might be suffering from dementia. He looks inbred and I've had unusual interactions with him in the past where he comes off as hostile. The guy spent around 3 minutes chit chatting with some teenagers ahead of me who were cashing lottery tickets. I get to the front of the line and the guy tells me that my stuff comes to $8.15. I hand him $8 and go to the change portion of my wallet for the 15 cents. At this point, inbred barks at me to hurry up. I've been at the front of the line for no longer than 20 seconds. He says this literally as I'm about to hand him the 15 cents. I put the 15 cents back in my wallet and ask him who he's talking to. He barks again in his broken English, "Hurry up, there's a line behind you" (this line had formed when he was chatting with the teenagers). It caught me so off guard that I just stood there and told him to fuck off. He mentions the line again and I say "well, that's too fucking bad." He repeats what I said, then I repeat it again. The whole thing was bizarre. He says hurry up another 2 or 3 times as I'm looking at him. I felt like throwing the change in his face or on the floor, but I just placed it on the table and walked out after telling him to shut the fuck up. Did I overreact? What would you have done?
