How about stress/anxiety? There's lots of reasons to get stressed out in stores like crowds, long waits, traffic, rudeness of other people, loudness, not being able to quickly find what you want, not getting out of the store when you think you should have, etc. I can't take my hubby shopping. He gets so nervous, that he has to go #2 so I have to quickly drive him home since he has a fear of germs. Crowds (lots of people) make him nervous.
