How is their contract written? If they are given X amount of dollars every year for a "uniform" allowance with no specifics on how it is to be spent, then it's the cities fault for negotiating a bad contract. If it is not spelled out what they can use the money for then they are taking it as just another benefit. I would question the store about how they are misrepresenting what is being sold as well as look at what the various contracts say.
Warm winds blowing, heating blue skies, and a road that goes forever, I'm going to Texas!
