I agree - I hate it when people try to help you out
But yea, I see where you're coming from - I don't mind the 1, maybe 2 people asking if I need help (then politely refusing), but too many times by the same person would absolutely suck. And waiting in line when there's 7 people standing in line is brutal - I like getting out of there fast, and not waste my time because these people are too lazy to get on a register.
One thing I hate about shopping, especially at Old Navy in market mall, is when the stores are messy and you can't find anything...you know, like the shirt sizes aren't in order, or it looks like a f'n tornado's gone through there. It makes a bad experience worse.
