That every store wants you to sign up and have you give them your details.
When I bought a shirt in a department store a couple of years ago and the guy wanted me to give him my email address “to save paper” (yeah right), rather than give me a receipt. It was like we were having a stand off for a while there. I just want to buy a shirt not sign up for ongoing spam!
If they get used it is obviously really going to be a bad time for all but one thing in their favour is that the prevailing wind goes from west to east.
