The Why of Fruit Labels

I know it’s a zombie, but I used to work for a hamburger joint and we got our produce delivered from a distributor in town. Every. Single. Fricking. Tomato had a sticker on it which had to be removed before you ran it through the slicer. It may save time at the checkout, but when you buy them in bulk from a supplier, it adds to the food preparation time when you have to peel the stickers off approximately 30 tomatoes in a box.
