My co-worker had her purse stolen yesterday. She was picking up takeout in a diner that is a long, narrow room. When you walk in, there is a counter along one side with stools. She set her bag on a stool while chatting with the servers. Another woman came in, ordered a shot (at lunchtime!), and walked out--with her purse.
My cafe bag never has to be "set down" anywhere. It's right there, draped over my shoulder. I wear it in front so I can see that no wandering hands get into it. And anything important is attached to it with keystraps and o-rings! (Except my Color Nook...might have to do something about that.)
I love my cafe bag. *curtsies*
