We all have heard stories of rude SA's who are so beeeyotch that most of the time you wouldn't want to interact with them. But if it weren't the case, is it rude to self-serve? You know, going behind counters and checking out the merchandise without an SA assisting you. Or is it more proper to stare lovingly at a merchandise and wait for an SA to approach you and help you out? I'd like to hear your thoughts on this.
