Consiglio del giorno che ti può essere utile:
If you’re given a paper receipt to add a tip and sign after paying with a credit card, such as at a restaurant, take a picture of how you filled it out!
This weekend I left a $6.00 tip on a bill, but when I checked my bank account the next day it had magically turned into a $60.00 tip! I called the restaurant and they asked if I had any evidence, to which I said no, but THEY should, because they should have the receipt and be able to see what I wrote down. They said they couldn’t find it (from one day prior), but after a while they did agree to refund my $60.00.
Going forward I’m going to start taking pictures of all these kinds of receipts after I enter my tip/final amounts!
