Thanks, Invictus and Lisa.
SerpentLust, that's unfortunate, sounds like you're better off being out of there. Silly of your boss to let you go too because many new herp owners don't realize they need some of the stuff they do and by you helping them, it may lead to extra sales. Also, a well informed owner is much less likely to bring a herp back because of health problems or because they realize it isn't suitable for them. Finally, if the customer knows you're knowledgeable and helpful, they will hopefully become repeat customers for all their herp needs from heat bulbs to possibly another pet.
