Just look go into a store wipe your hands and buggy.Then shop pick up bottles,cans,packages etc.Then check out.Either card or cash.Get $$$ out of your pocket,get change back.Even with card you get reciept or have to enetr number etc on machine.Oh then go home and handle everything again.Its alright to be careful.But not going to become a bubble boy like on Sinefeld.Rocky
