There's been a couple of times when I wish that it was the case. Once, on a six hour flight with my baby daughter, when she used up all the diapers in our cabin baggage and I was getting seriously worried. The second time was my first and (so far only) first class flight on Swiss, when I spent more time in the lav than in the seat.
