I completely agree. When I go to a store, I like to be left completely alone and just browse at my own pace. It makes me so anxious when the workers come up to me and ask me if they can help, even if they're just trying to be friendly. If I really, absolutely needed their help, I'd ask, otherwise I just want to keep to myself.
Sometimes I won't even go into a store if it's really empty, because I'd be the only one there and the employees would flock to me or at least I know they'd be watching me the whole time. I prefer stores that are a little more crowded (but not too crowded, because that makes me anxious, too
It's best when there's just the right amount of people.)
