I literally just learned last night that the little table is to hold the slice next to yours as you pull a piece, that way you’re not touching the next person’s slice with your grubby ass hands.
Maybe I should’ve said that you CAN use them as a way to avoid touching two slices when pulling your own. You pick it up, place it in the middle of the slice next to yours, and pull so you don’t touch the crust of the next persons slice. Probably a creative use for something that was originally intended to keep boxes from saggjng
It’s meant to be picked up, the feet placed on the next slice, and you pull your slice with your hand. It’s not like it stays in the middle.
I worked in pizza places for 10+ years and we never used them, so maybe their original intention was avoiding pizza box sag, I suppose I wouldn’t know. I guess we can just say using them to not touch the next slice as you pull your own is a more creative adaptive use
