GNC and other mall stores..I never tusted the people who work there. I always consider them just mall workers, workig in a store at the mall. No knowledge of the product they are selling.

I went into Vitamin World and saw a girl working in there who started workingout at the gym. Before I knew she was working at that Vitamin World she as asking me all about diets and working out...she really had no clue what she was doing. Then a few days later I saw her working at Vitamin World giving advise to customers about nutrition adn vitamin dosage.
Right then and there, I figured all people who are working at 'mall stores" are just that...mall workers. No clue what they are are selling.
