Ugh., that would piss me off. I'll never grasp why people get pets they don't bother to learn anything about. I get asked for reptile advice a lot at my local pet store because I have herps and one time this lady was there looking for heat lamps for her snake and wanting to know which was best. She didn't know what kind of snake they had, what the current temps were (no thermometer), but she thought it seemed cold and was just going to make it hotter. Wow.
