of course, the "must be alert for the critical after-midnight work" imperative does not mesh well with the "must get to sleep immediately after work so i can be alert first thing in the morning" imperative, especially when the drunk people show up at 4am trying to get through the door of your hotel room. again and again. and again. enough to get me out of bed and trying to decide whether to bother putting on pants before opening the door to tell them off.
designated drivers is all well and fine, but whatever happened to designated hotel-room-finders? you never hear about them anymore.
