Actually now that you mention smaller size, I think you're onto something. I tend not to go to chains & big establishments, usually they're more like independently owned neighbourhood bars, etc. They probably don't wanna spend the money or maybe they just can't afford it. People do get insanely stupid while drunk, my buddy tried to start a fight with a bouncer 1 time & I was practically begging the bouncer to not go after my buddy. Good thing the bouncer was a reasonable guy, he was well within his rights to beat the crap out of my buddy.
