I hope I'm in the correct forum for this ...
I went to Leslies to get a wall whale at lunch. (Saw they were on sale in another thread). This was my first trip so I asked Jonathan if they sold liquid chlorine. Jon and a buddy descended on me like wolves. It was the same conversation I've read here a dozen times, starting with 'You can't put that in your pool' (I laughed once and caught myself) and ending with 'well, ok'. During my systematic destruction of his arguments with my rudimentary knowledge of BBB, he did manage to ask "Did you get this from an internet chat room ?" to which I replied, "Yes, Troublefreepool.com, it's a good read for anyone with a pool".
Anyway, the best moment occurred as I was signing the receipt. A contractor had been standing next to me having a somewhat tense exchange with a clerk over returning a pump. He leaned over to me and said "Pressure Works on Roseneath" as he left. Sure enough, I looked them up, they carry chlorine in carbouys, but I don't have a price yet. Jonathan had pretty much had it with both of us and handed me my receipt with a terse 'thank you'.
