Went in already having worked for a Leslie's in the past but forgot about some of the different products. I needed a shock that would remove all the \""used\"" chlorine and leave all the free chlorine in the pool. Only one kid was working who didn't seem to know anything about it and was arguing with me saying that what I was saying was not true. So I went down to nps across the street (fully staffed) and the first guy I talked to was very knowledgable and helped me out. Leslie's needs professionals. Not low paid kids with no knowledge.
