Yes, 100% of the time! Drives me batty when I see someone fully capable (meaning no kids, handicap, etc) either just let it roll or hike up in the grass or something. I once was parked in my car getting ready to get out when a lady (across the lot) just let her cart go after she put her groceries in the car and the cart ran right into my car (as I'm sitting in it). I was p!ssed! From then on, I vowed to always always put it back!
