I totally disagree that you can look at a fish at a LFS
for a few minutes and tell if it will be okay. If it looks bad, obviously pass, but things like Ich have parasites that spend more time off the fish than on.
I'm honestly all over the place with QT. I have a 35g that I've used for many fish, but I've also had fish that I've seen at the LFS
for weeks and kinda felt that counted as QT. I've observed fish for 2-3 weeks in my QT and put them in my tanks and have done the 5-6 with others.
That being said, I've had one tank years ago that got something and it wiped out over $800 worth of fish in less than a week. I've had lesser catastrophes too . That's no fun.
It all works fine not QTing until it doesn't. If you don't, then you have to be cool with the loss.
