I appreciate that you took the time to come over and talk to me and see if I needed anything, but I would like it if you didn't try to guess what I'm in for. Walking up to me, making a pained face and going "oooh, honey, you need some skin help don't you? You should try [brand]" may have seemed helpful in your mind, but actually hurt my feelings and was, in my opinion, rude and inappropriate. I know you're supposed to suggestively sell, but come on!
And I wanted mascara anyway, so lah-di-dah.
