No.
Not alcohol-free anyways. Believe it or not, you can get a dirty cheap drink in Vegas. The cheapest is the Crown Royal Black iced tea which they’ll serve you for free at pretty much any bar that isn’t Bally’s or Paris. There are even certain places where the bartender will duct tape your head back before pouring vodka down one of your nostrils and rubbing some magic potion on your feet to cure whatever ails you before finally tossing in an aspirin so they don’t have to look at you for too long afterwards. I agree most drinks cost way too much, but most people suckers for paying more than most other cities just because it has casino lights all over the strip lighting.
