When I was in the back of the Boeing, we were doing the MEM-BUF-Ottawa trip. The sort was late, so we were late getting to BUF. When we got there, customs paperwork for some cargo from China was missing/incorrect (not our fault, this isn't the paperwork we check for). We were delayed while they worked throught that (everyone in MEM was gone by then, ramp in ANC was not staffed then, so no one to help.) After drooling for over an hour, the f/o said, no way. We are going to the hotel. We had an 8 hour nap at the hotel, and continued to Ottawa. Never heard a thing.
