I have a concern

[kmj]

Hello all! I'm new to the forums and to all of this, actually. I've had my corn snake for almost two years but as much time as I spend reading about all kinds of snakes, I'm hardly an expert. So I came here for opinions on something. I went into petco today and what I saw bothered me so much that I joined this forum just to complain about it. I'm not fond of petco in general but they had a sale on something I needed. I was looking at the snakes, of course, and came across a Colombian red tail boa that looked straight up emaciated.

There was zero muscle on this poor guy, skin was sagging and he could hardly move. I called an employee over and asked her what the deal was and she said "oh he's just molting." I can say right now that I have never seen my snake or any other snake molt like that. Since when do snakes lose all muscle when molting? The pics don't even properly show how starved he looked. Can you guys confirm this, am I freaking out over nothing? And what should I do (if anything) if this snake actually is starved? Just came here to vent! Hi to everyone! Hope I'm not breaking any rules already~

I have pics but apparently I can't post them?
