I don't put anything on the floor, especially my bags! A member mentioned ones that she even places her bag on the floor of a public restroom .
I'm a germaphobe so I don't think I can ever be too careful!! I try to NEVER put my bags on the floor just because I shudder to think where people's shoes (including mine) have been! I'm sure my family and friends think I'm *a little* paranoid but hey, it's what makes me and my handbags happy!
