There's all sorts of things, even as an ordinary TM. The store is open 100-120 hours a week, we minions are scheduled for an average of 30 hours. That's a lot of time that something that even a minion know needs to get around. I go home, I have to plan how I'm going to go in and handle a pre-holiday or post-holiday fitting room, I have to remember which mannequin I took an item of clothes off of so I can tell the VM, I have to check if the clothing item with the swapped tag that I told whoever was taking stuff up to the front was an AP issue actually made it there or is back at the fitting room or (even worse) on the floor, I have to go in knowing what Cartwheel offers apply, all sorts of stuff.
Anyone who clocks out mentally when they clock out physically isn't able to do that because there is nothing to mentally take home, they just don't care about the job. That applies to nearly every job out there, maybe even all.
