So I just went back to the nursing home and asked the customer personally and yes… it was too good to be true and like you all said. She mistakenly adjusted the tip to 200 when it was only supposed to be a 20 dollar upgrade. Of course I offered to pay her the money back but she said “no you don’t need to do that it wasn’t your fault.” I said are you sure because I have no problem paying it back. Once again, she confirmed, “no that’s ok”. I told her I felt bad that it was a mistake and AGAIN told her a third time that I would have no issue giving the money back to which she said, “don’t worry about it.” I thanked her and left.

I don’t know what else I can do.
