I bought a car battery there once. Just that. Had the receipt in my hand. Carrying the battery in the other. Dude stopped me to check my receipt. Because I'm not a dickhead I just showed it to him, but it was funny that a couple dirt balls pushing full carts of likely skip scanned items walked past during this.
Funny story about theft. When I sold electronics at Sears back in college one of the Appliance guys across the aisle had worked at a big outdoorsy type store previously. Like a Cabela's or Scheels, something of the sort, don't remember where. These two guys jacked an entire canoe. No one noticed. How'd they get caught? They came back in to steal the oars. Someone noticed them walking out with them and saw they were heading to a truck with a shiny brand new canoe that the store carries sticking out of the back of it. So they called the fuzz, they stopped the guys, rolled back the security footage and sure enough 10 minutes previous these guys came in, each grabbed an end of of a canoe, and walked right past everyone out the front door. If it takes two people to carry something out the door past staff during business hours no one really questions it lol.
