It might be rude, but it's not the cashier's place to reprimand a customer. Where would it end?
Mr Dotsie always rings me when I'm paying for something, it's like he knows that money is leaving the account
I always say I'm going to take the call, then I take it. Considering how little interaction most cashiers engage in, I'm surprised she cared anyway. Has she ever served anyone whilst chatting with another member of staff? Would she reprimand anyone who did?
