I was at Dallas Fort Worth airport last week. The entire airport is cashless. Since it was business travel I use AMEX for everything.
I ate at a tgi Friday restaurant that expected me to self checkout with their app.
I should have whipped out some cash and told them I lost my credit card.
I did send an email that I won’t be returning. Since the waitress didn’t have to provide as much service I also told them my tip was lower.
