True. "Mom and Pop" shops are more likely to have knowledgeable staff, usually it's someone who's been in the hobby so long and love it so much they make a living out of doing it. Mainly I was assuming we were discussing "big name" pet stores, and in my experience those employees are simply trying to make a sale, and passing along whatever info they've been given to pass along. Like I said, there is definitely the minority of employees that are experienced and knowing, but this is far less frequent than the opposite scenario.
I'm sure there are people on this forum who are inexperienced as well but so far the original poster has gotten good advice from some experienced members and I was just trying to imply that they specifically probably knew what they were talking about more than the pet store.
Part of being a good pet owner is taking in all the information you get, good or bad, and sorting through it to figure out what works best for you, and your snake. Everyone's knowledge and skill levels are different but the information is out there
