S= my sister
C: you didn't buy that much candy and you're paying with a twenty?
S: it's all the money that I have...
C: don't you know that you should never buy a dollar worth of stuff with a twenty?
It's not a ton but she had a super bitchy tone. And it's not like she didn't have any small change in her register- I made sure to check when she opened it that she had plenty of small bills. I didn't think a twenty was really that big of a deal- she only lost a ten, a five, and three ones. Plus we were the only people in there in the ten minutes we were there- shouldn't she have been more happy with our business?
tl;dr: lady is a bitch when my sister tries to buy $1.50 of candy with a twenty.
