This would be bad publicity amongst shoplifters only.
Condiments are generally for purchased items that they make sense to be put on; e.g. you wouldn’t get a packet of coffee creamer for a hot dog, but mustard and ketchup would be assumed OK. Cheese sauce on chips, when the sauce is not marked for a specific use or sale, makes a kind of borderline sense at a store that sells the chips. (People used to think me weird for putting mustard on potato chips.) I think the guy had a lousy lawyer.
