The legislation is already there to refuse sale without water samples, inappropriate existing tank mates e.t.c. The animal welfare act already covers it. It's words to the effect that if you buy or sell an animal into conditions that are inappropriate to it's requirements, you are committing an animal cruelty offence. I personaly have refused many sales in the 19/20 months I've worked in aquatics retail, on these grounds. One that stands out most was a gentleman whom was trying to buy 5 bettas. As usual alarm bells were set ringging in my ears, on the following conversation insued;
me; are they going into the same tank?
customer; yes
me; you do realise that they will fight, usualy to the death when put together don't you?
customer; yes, thats cand of the idea
me; I can't sell you any then I'm afraid
customer; why?
me; because it would be selling you fish that aren't compatible, and I'm not allowed to do that
customer; just give me the dam fish
me; lets re-phrase that a bit shall we. Under the animal welfare act, it is a criminal offence to knowingly sell or buy any fish, that will then be placed into conditions will caurse harm, suffering or distress to that animal. Putting Bettas together will lead to all three, therefore I'm formaly refusing you sale of those fish
customer; ok, here, £10 to say you didn't know that. What do you say?
me; I think you'd better leave before I get a chance to call the police
customer; this is an f*?!ing shop, you sell fish. What a rediculus place when they don't let you buy what they sell (loudly and walking away)
Some people are unbeliable......anyhow, the legislation is already there, and I have personaly had to use it before. In this instant things went OK, but when some of my colegues have used it in the past, they have been subjected to violent assaults from customers. Just because the legislation is there doesn't mean that it is always used. Some of my colegues are afraid to use it after some previous incidents that they have been involved in as a result of the use of the existing act. The problem isn't always shop staff...
Better training and awareness has to be used realy to avoid issues, and the shop has to give their employees support when they use the legislation as some nutters do not take being told no very well

With training, P@H would probibly be a good store, but in places like that training is not practical with the complex subject of fish, due to high staff turn-over

buy the time staff have finished training, they would probibly have handed in their notice
All the best
