When I ran a store I wouldn't sell anything until it was eating strongly. It might mean I had fish for a few weeks but everything stayed with me for a minimum observation qt anyway (apart from special orders where we'd arranged for the fish to be taken in the wholesale bag with no guarantee for a discount).
It seems crazy to sell them right away and the shops that do around me now all have terrible reputations.
At the weekend I had some defrosted food in the fridge for if people wanted to see things feeding. It's not hard to drop a few mysis in a tank and we deliberately didn't feed in the morning so they were hungry, we'd then do a proper feeding at night when we'd closed to make sure they were fed but they normally got fed properly throughout the day.
If I see something I want now that is new in I just reserve it, pay a deposit and pick it up later. If it dies before I get it then it would have likely died in my qt anyway.
