Ahhh, Burger Chef!
I was a 'teen worker' at our local burger chef.
Burger Chef was a franchise that was bought out in the late 1980's, by Hardees. The independent owners were able to buy a few more years of use of the "Burger Chef" name, and then had to either convert to Hardees, or change altogether. Our local Burger Chef went independent in 1994, but they still use the 'hat' logo to punch holes in the 'family size fry' bags!
I still have a couple of different aprons from the uniforms , my name tag, and a couple of employer christmas presents with the burger chef logo. I still have a white tshirt, and a small cooler, both of which are still in the plastic. I wonder if there is a market for this stuff?!?!?!?
