Sounds like when I was a cashier and when I had hold up the money to make sure it wasn't counterfeit the customer would, without fail, say "HAHA I JUST MADE IT THIS MORNING." And laugh like it was the single funniest joke in the entire world.

you laugh at their jokes, dammit.

That's a pretty original joke

I occasionally make lame jokes like that and am usually a little embarrassed of myself afterwards. Can't imagine wanting to repeat the whole thing to management.

That's why I had a pre-recorded laugh-track ready to go whenever a customer made a lame joke. I'd hit that play button and stare at them as laughter from long-dead people filled the store. It was glorious.

"I'd like to launch a complaint. I told one of your cashiers a joke. They asked for my ID, and I said they couldn't have it." "…" "Is there anyth—" "AHAHAHAHAHAHAHA! I JUST GOT IT! Man, that is some witty humor. Fuck! It took me a second. Wow. Woooow! Did you write that yourself? AHAHA, I just remembered the part where you said they couldn't have your ID! Classic!"

Must be some needy asf neighborhood you're working in for someone there to complain you not laughing at their joke

I hear ya sometimes the old jackass's joke ain't funny and it gets old listening to it and plastering a smile on your face!!!

I would just laugh uncontrollably for about 3 minutes as if it were the funniest thing in the world. Be sure to compliment the customer on their originality.

When I was a cashier people would walk up and say "Oh you're just waitin for me, aren't cha?"
