This brings back memories of working the night shift in retail. The store I worked at had a massive stockroom that was big enough to do shit like this with the pallet jacks.
Oh yes, I do remember playing around on pallet jacks at my nightstocking job. Oftentimes they're the fastest way to move around a store. The only problem is that you get fired if you slam into a customer. Aside from that, there weren't any rules about not using a pallet jack like a crude scooter.
