Saying that this bathroom is limited to the customers of the Saxby’s Coffee at Vermont Avenue and K Street NW seems to avoid the more pressing problem — who the heck would want to use a bathroom that so blatantly encourages peeping? Worse yet, how is it that this sign has remained on the door since September 2010, when TBD’s Amanda Hess first spotted it?

A tipster asked us the very question, and we’re also scratching our heads about it. The most we can offer is that the sign seems to have some international appeal.
