As long as it's right for you... who cares
My worst bugbear is stood behind someone at a till, waiting for them to A) fumble about trying to get change out of their wallet, have so much stuff in it it takes them 10 minutes to find anything, C) Pay for a pack of chewing gum with their card,
and D) start doing points A to C when the cashier says that will be........ 32p please.
PEOPLE YOU KNOW YOU ARE GOING TO PAY FOR SOMETHING.... SO FOR FECK SAKE PREPARE !!!!!!!!
