We just bought a brand new tank at Home Depot, the cashier asked if we would like it filled since we were there I figure it would save me a trip to the local nursery where we I always go. Little did we know it was an exchange, the guy was going to give us a used tank when iwe just bought a new one, well now we had to go back inside and stand on the return line for 1/2 hr to get our money back because the jackass didn't tell us they exchage and not fill yours.
