You shouldn't hold the sales associate accountable at all what so ever. Be nice you have no idea what kind of jerks people in retail have to deal with. It's insane they are following what they were told to do to keep there job. Instead be nice to the cashier and kindly take it up with the manager. Kindness goes a long way.
I agree. Felt bad for the girl who was asking me and who kept apologizing since I knew what I wanted. Told her its okay... do what you have to do because I'm sure you are being "forced" to do it
