I used to be a cashier for Sam’s Club in Missouri. Same thing here.
We had this guy who was a semi-regular. He didn’t have a membership, he’d just come every once in a while and buy a shitload of alcohol. One time he went through my line for it, so I hit the button to call my supervisor over and we’re waiting there while she’s finishing up talking to another customer. We’re sitting there for maybe 15 seconds before he walks his ass all the way to where they’re standing and tries to get my supervisor to come over immediately. They both come back after a little bit, she puts in her thing, and I start scanning. I scan each bottle like I’m supposed to, then I tell him his total; and he starts acting like I must have messed up and scanned some a couple extra times.
This motherfucker watched me like a hawk the entire time, my supervisor was standing there the whole time, and to top it off he tried to come behind my register to look at my screen and “make sure” I scanned it correctly. Both of us had to tell him to back off, and he finally had me remove some of the bottles I scanned so he didn’t have to pay as much.
It was a whole thing, and the dude was insufferable and entitled to the max.
