A friend was very happy the other day. She had given £5 in a shop and the sales assistant thought it was £10 so she got extra money back in change. She thought this was funny and great to have extra money! I said did you take the money back to the girl and she looked at me as if I had two heads. No she made the mistake not me! But the girl may get into trouble for it later and have to pay the shop owner. She did not care and just laughed. I was suprised as this was someone who normally seemed nice.
What do you think? Should she have kept the money as it wasn't her mistake or should she have said here is the money you've made a mistake. What if my friend was poor and needed the money?
Do you think many people do what she did these days, have thinngs changed?
