Luggage Savings

My name is Lucky and I am a student working at Wally World.

I have noticed, and kept record of the following: I have noticed that blacks, in general, request bags for things that don't need or are too large for bags in general.

For instance, you know those big ass rolls of TP or paper towels? They'll want bags for those, regardless of the fact that the plastic bag only covers one fourth of the aforementioned items.

I was wondering if anyone else who has worked in retail can explain this phenomena to me.
But, if the customer wants extra bags I will give them away. It's not sweat off my back.
Groceries are food items, dear. I’m talking about large, non-food items, in particular, large paper towels that will not fit inside the plastic bags on the carousel.
