Dear LFTP: coworker takes shared research materials into the restroom

• Is taking shared workplace materials into the bathroom gross and inappropriate?

A listener asks whether she's crazy for being grossed out that a coworker takes shared company research books into the restroom multiple times a day for up to half an hour. The hosts mostly agree it's gross and unsanitary, note the coworker is probably just wasting time, and role-play confronting him. The secular answer says to take it to HR or the boss — advice the hosts find unhelpful.
