Tale from my training days. So I'm like 2 weeks new. I have two customers, both men come up to me I ring em up, they wanna split the payment. Okay. Cool. We do the math, i charge the first guy the first half, the rest is different by a penny. I'm sleepy and adjusting to graveyard shift. So i type in the other split payment by the math. I'm about to let them go when I realize the mistake. And here's where it gets crazy.
Me; Uh sir? there's a penny left.
First man: Oh okay. (Goes to get card again)
Second man: Wait what do you mean a penny?
Me: Apologies sir. i typed in the amount split, rather than the amount total. I just need your friend to finish up his payment-
Man: No! My friend is not going to pay a penny on his card cause of your mistake.
First man: Really dude it's fine.
Second man: No it's not! Starkiller11240, is that your name?, you messed it up. You should pay.
Me: I- huh?! I'm sorry sir i'm broke at the moment I can't pay-
Second man: Well then get me a manager! I'm going to talk to them about this! This is horrible customer service!
me: pages over walkie for a manager
First man: Just ring me up. i'll pay. (He paid thankfully)
Me: Okay then. calls off manager over walkie Second man: No! Get a manager up here!
Me: calls again for manager
We waited a really long while for a manager. While waiting I tried to help a customer with a money order, which the second man took as me trying to wriggle out of the situation. Manager came and second man starts ranting about customer service and how his time is more valuable than being wasted on checking out (this was 2-3 am. On a weekend). He went as far as to suggest I be fired as I had misrepresented my store company.
My manager just sat and nodded, listening. He repeated the story to my manager, making a lot of stuff up about what I had said to him, which I firmly countered with the truth while still helping the other customer who was awkwardly listening to the whole thing. He finished his nearly 30 minute rant and left, as my managers walked him out.
Afterwards my manager thankfully told me to just "In one ear out the other" it, and resumed my duties.
