Most people are far too busy worrying about what other people think about them to even notice what bag you're carrying and judge you for it.
I think most of us think people notice us WAY more than they actually do.
That reminds me of a quote I heard on Dr Phil (LOL, yes I admit it - I am guilty of watching at times!) years ago that stuck in my head:
"You wouldn't worry so much about what other people think of you if you realised how seldom they do."
