I once sold a tub to two teenage twin brothers. They had their own Townhouse too. I am certain their parents were well to do, but these guys had their own money.
They were part of a "boy band" called Before 4 (or B44 i forget). They had limitted stardom in Canada, but mostly performed for their fans in Europe.
Funny guys to say the least. They would call the store from Europe to check and make sure that their friends were bringing water for testing and taking care of their tub.
