I was checking out and had a 25 lb bucket of 1inch tablets and anothe 25 lb bucket of 3 inch tablets. I was told i per customer and i replied that its 2 different sizes. And the cashier said " its people like you is the reason why there is a shortage of chlorine" I replied "excuse me people like me" What did he mean people like me???? I then told him i will be back tomorrow to buy the 3 inch tablet 25 lb bucket. He said " i wont sell it to you" i said im a customer plus im coming back tomorrow and he said " i wont sell it to you because i will recognize you" THIS IS UNCALLED FOR I WANT ACTION!!!!!.
