I've taken Ramses to the mall before, but only during the summer when it's warm enough. And I don't take him to the food court, and if someone is afraid of snakes, I respect that and stay away from them, then try to explain to them from a distance that there's no reason to be afraid XD
I also took him to school on the last day last year. My school is a marine biology academy, and we've got an iguana, a leopard gecko, and several dozen turtles throughout the building, so bringing a snake in wasn't that big a deal. In fact my Spanish teacher found him incredible, and my history teacher tried to run off with him and I had to chase him down. XD My leopard gecko also came to school, but that was for a presentation I had to do on leopard geckos, so I suppose that's different.
