Welcome to our community. No, we're British through and through, although we probably do have more members from the USA, but it is a much larger country.
Right, after reading your post, I am absolutely seething angry, really, I really want to know the name of the shop that told you to flush the fish down the toilet. I am going to name and shame these bastards and make sure everybody knows who they are.
Please do not flush any fish down the toilet, it is unacceptable and totally inhumane.
