If you love it keep doing it. Don't let a bunch of frustrated atheletes deter you from having fun, or making some extra money. Besides, why would being out of shape makea difference? I don't know anyone who can outrun a sherriff's bullett!!!! Maybe you can have some of the big boys come watch you work dressed in full uniform. I'm guessing the jackasses on the floor will change their attitudes then. Have fun - Suppref
