I'm trying, trust me.
They want us to help guests, so I greet (I'd estimate) 80% of the guests I see. Not all of them, but plenty, need to be guided to what they want. That's time off doing a U-boat. Then add in the garbage (worse if you're in home, you guys who have been in the lamp/mirror areas know what I'm talking about!) and cardboard, and the disposal of it. Even more fun if some bozo has loaded the baler improperly and cardboard slides right out.
Backstocking, because you're ALWAYS going to have some. In one 4 1/2 hour shift you just can't get into a good flow and get much done.
I'm not the fastest person, either.
My job search has ramped up, to say the least.
