We're advancing in the other direction. The point is, of course, that no two people see the same thing in the same way. Strippers, for example, view men as hopeless morons oozing wads of cash. Men see strippers as potential dating material. Bartenders and barflies answer this question quite differently.
Bartenders universally dislike loud, brutish behavior.
You risk pissing off the bartender by yelling or tapping your glass. All bartenders, in fact, suggest a subtle wave of the hand. Cool River doesn't really attract the big bandit crowd. When we're really busy there's no way the bartender will know who's next. Just relax, we'll get to you.
