The Betta situation in my local Pets at Home is dreadful. They're put in rows of tanks so they can see eachother and make eachother flare, which is extremely cruel and stressful for them. They are all in poor condition with ragged fins and dull colours, and tend to just hang there.
I don't really like going into Pets at Home because it's kind of depressing. Loads of families taking the staffs' bogus advice and buying the wrong fish for the wrong tank. Plus there's loads of horrible 'starter kits' which are far too small for the fish they're advertised for and have cheap, nasty filters. Ugh.
