I had this twice in the same day the other day. Was travelling, had cash to get rid of and the poor teenage cashiers these days can’t wrap their brain around the concept at all cos they never had to.

I could watch their brain rebooting, give up, punch it in the till and then be really baffled when they hand me back a 10 euro note.

A good number would just comply
