Its only purpose is for recognition. That is, recognizing the workers in an instant due to familiarity and exposure from previous times you've been there. For example, if you go to Best Buy one day all the workers are wearing the same uniform and they will still wear those same clothes when you come back whenever. This establishes consistency for the customer who will come to your store regardless of location and time rather than having to find out who is a worker when normal customers themselves could very well be dressed similarly to a worker.
