Very well saidI'll be honest here and say that it does not sound to me like you've done very much reading on this site due to the key points we reiterate over and over being completely missed by you somehow. You say you're surprised to hear if the 3 meals rule for handling and yet it is one of the most repeated pieces of advice...
We are very avid at telling people to use thermostats for ALL heat sources (glass getting too hot on UTH is NOT possible with a thermostat unless you as the owner set it improperly)
Also, we ALWAYS tell new owners to handle only after 3 consecutive meals at a normal interval. Before this, they're still settling and handling could add just enough stress to give refusals that early on.
There are threads from just about every week where one of us has posted one or both of those things for the entire time I've been on the forum. Sometimes several instances in a single day.
Deb is among the most experienced on here and has had to tell hundreds of new keepers over and over this same information. It is not intended to be condescending, but it is brisk and to the point (after repeating yourself so many times, I'm sure you'd also be rather blunt about it). The threads she linked were created for the purpose of giving new owners good resources to follow, particularly for trouble feeders.
I advise you take a step back and consider the advice above to be given in a blunt but helpful tone before responding. Tone is often lost in text, so it is easy to read something as more harsh than it was intended. Being defensive of criticism or suggestions does not help anyone and we truly do want to help your snake.
Everyone here has made mistakes at one point or another, but the key is to learn from them and be open to learning what does work when you find you've made a mistake.
Keep in mind, there are plenty of bad pet owners of any type. Just because someone managed to keep a snake alive doesn't mean that they necessarily have ideal husbandry or techniques. Not saying your pet store employee IS a bad keeper, but some advice is outdated now (i.e. red lights on 24/7 is stressful since snakes do see red light. This was not previously known and was commonly advised and is now less than ideal husbandry to use constantly. Isntead CHEs are advised as they emit no light.) There exist poor owners with seemingly healthy snakes who think they're doing everything perfectly.
