I suppose it is possible to live without cash in the days of cell phone wallets. What do you prefer cash, checks, credit cards, crypto-currency or phone based pay mechanisms?
I ask simply because I am in an airport where the restaurants force you to pay on card. It does make it easier for the staff as they don’t have to make change for anything. However, I suspect it also drives up the tabs because there is science that shows when you use plastic you will spend more.
Thoughts?
