Ahh, I saw your posts on Tumblr. It's really upsetting that they did that to the one with SBD. I'm sure he had a chance of survival, being so active and could have recovered or lived comfortably under your care. The employee might have seen him and thought he was a goner or already dead. Still pretty careless, the poor boy must have perked up at the sight of the person before suffering that kind of end.
I find it hard to visit the Petbarn near home, they don't supply as much in variety and the fish always look sick or have fungus growing all over them. But it's never as bad as what you've got there. The betta here are kept in small 1/2 gallon tanks and still look better than the ones sold in cups. Thankfully though I found a bigger and better pet store nearby that stock higher quality products and keep their betta, in jars hooked up to a drip/small flow system that changes the water slowly as time goes by. Those betta seem to be very bright and active with no illness visible.
