person A: Last summer I stayed with a friend as I was nearly broke.  I went the store to get food and got back $20 extra in change from the cashier and ended up keeping the money.
person B: Oh wow_comma_ so it was extra money that was not yours?
person A: Yeah so her drawer was short. I realized it later not while she gave me the change so that helped me justify keeping it.
person B: I hope she didn't get in trouble for being short $20. 
person A: Yeah I thought about that. She was still working there weeks later so I was happy she wasn't fired.
