I can laugh at John McNamee's comic, but only because I don't work in a public library anymore.
It may be for the best. Some public libraries are building freestanding erotica genre sections and providing erotica readers' advisory services. The Seattle Public Library, at one point, openly supported the right of patrons to view pornography on public access computers. These are complications I would rather avoid.
The bathrooms are around the corner and to the left.
