"It's vulgar, offensive, and disgusting and I demand you take it down right this minute," the woman on the other side of the bar shouts at you.
"Ma'am," you explain, "my complete lack of interest in what you find offensive aside, I'm a barback. I don't have the authority, training, or inclination to take down the sign on the bathroom door."
"It is an obvious depiction of the male genitalia and it is completely inappropriate!" she scoffs. "What if a child comes in here?"
"Into this bar, ma'am? Then I'd imagine seeing a suggestive picture of a microphone is the least of that child's worries."
