When I was in LTL I loaded at a large hair care products manufacturer first thing in the morning. It was a live load from a conveyor belt to the floor of the trailer. Every Christmas they gave me a large box of hair care products; shampoo, conditioner, hair spray, gel and moose. A couple times during the year their regular truck load carrier would get jammed up and couldn't get in to spot trailers. I would spot a trailer or pull one from the dock for them and in return I would get a grocery bag of hair care products. I not sure if they appreciated me or took some perverse pleasure in giving a bald guy all that hair stuff.
Pearson Candy always had Salted Nut Rolls for the drivers. I think my favorite was Everfresh Foods, maker of China Boy chow mein noodles. They always gave me a bag or two of noodles and an open box of fresh from the ovens, steaming hot chow mein noodles.
