Extremely rude. I called asking for a diagnostic service to be followed by a weekly cleaning service for my slightly(very slightly) green pool that just had all the equipment replaced last year. I was told the initial coat would be $300 and that my sand filter is "horrible" and my plaster pool is "screwed." I was then berated for all the issues he has had with past customers to the point that I just hung up. How do these people get into the service industry?
