Two recent visits to Wagamama (outstanding noodle bars - give them a try if you haven’t already) have uncovered a strange habit: when asking for the bill, it’s brought immediately to your table, with a slip asking for the tip and a signature. Once this is filled in, your credit card is taken away briefly - presumably to be swiped. But no further signature is required, and even more surprisingly no PIN number is requested. That’s the end of the transaction.
Is this legal? Is it within the terms of the merchant agreement? Is it sensible? Is it secure?
I don’t know, but it’s sure weird. I haven’t seen any other merchant do this.
