A couple short ones
I'm the customer in this one. I'm going to a Pita place to eat.
Me: Can I get a chicken ceasar pita?
He opens up a pita and asks what vegies I want in it.
Me: Uh... Lettuce. And Ceasar dressing probably goes in it too, doesn't it?
So he puts the lettuce and dressing in.
Him: this is all you want?
Me: Well... The chicken and bacon too...
Him: What are you getting?
Me: A Chicken Caesar pita.
Him: Oh, I thought you said veggie!
How the two words sounded alike to him, I'll never know.
At work yesterday. My first customer wants to do 2 transactions for her stuff. He first total comes to $49.xx. She pulls out a hundred dollar bill. As is normal at the start of a shift, I only had 5s and one 10 in my till, so I ask her if she's OK with receiving lots of bills in her change. She realises at that moment that she's handing me a hundred instead of the 50 that she intended to pay me with, and switches the bill. She pays for her first transaction with her 50.
So I scan her second lot of items, and that total comes to about $30-something. She hand me a hundred dollar bill. to make change, she got her 50 back from me, that spent all of about 30 seconds in my till.
As she was paying, she actually realised what happened and laughed about it. And before any one suggests it, the bills were real, and she didn't do anything suspicious to make me think she was trying to scam me.
