Completely agree, I don't blame the staff though, it's managements responsibility to make sure staff are briefed appropriately.
I went into McDonald's again (same branch where I first used Apple pay a week ago to be confronted with "we don't take payment from phones" I'm not an argumentative type but did state, well I used my phone last week and you have apple pay stickers in the window, he response "we used to accept it but we've stopped now as it takes too long"
Translate to mean "I don't know how to work the till properly"
