Not me - I see no reason to take them in public - it certainly isn't a stress free experience for the snake, and I don't see any benefit for the snake or myself to expose it to who knows what at the pet stores.
Usually when I see someone in public with a snake, it's usually to get attention. And since the general public doesn't understand snakes, they get attention, and you generally can see them enjoying the shock value carrying their snake in public gets them.
I personally prefer the relationship that I have with my snakes in my quiet home environment, without negative attention from the public.
But to each their own, I guess.
I've also got 50 snakes, and people's reactions range from grossed out to fascinated.
