I've actually had drunks try to grab my arms from over the bar to check out my tattoos, while I am serving drinks...This has been both women and men and it pisses me off, because I swear, it's like being drunk gives you the sense of entitlement to touch and pull at things that aren't yours. My bar is right next to a tattoo shop, too, so the culture is pretty standard here in Seabright Santa Cruz.
I've seen drunk guys comment on girls tattoos and then proceed to bury themselves in the process by backhanding complementing the tattoo.
