Before I retired as a Safety Consultant for a large unnamed retailer (they throw a big nationally televised parade at Thanksgiving), slips/trips and falls were a frequent cause of accidents and injuries for both customers and associates, usually from rain or snow carried in or tags or hangars or other debris on the floor. To minimize accidents, I instilled the idea of “if you see it, you own it” to get associates to keep the floor free from hazards. I told them it was easier for each person to pick up 1 or 2 things off the floor rather than 1 person having to go around to pick up 50 things.
I try to clean my own messes at home, and now that I’m retired and a fall might injure me, I pick things up when I see them.
