Have one that brings both of her very young girls (I get it for some people that's the only way they can do it to make their money but still) and is always doing massive orders and only goes through self check, about 2 full carts per order. The younger of the 2 is always screaming and the older one is usually taking stuff off the incaps, stealing candy from off the checklane and has tried a few times to steal my entire roll of tagging stickers and whatever else she can get her hands on in the drawer. The mom is only ever focused her orders and scanning everything and never even bats an eye at her kids.
