The FA knocked three times on the F crapper door recently after one particular person had been there for 20 minutes and the other crapper was blocked and out of service. On emerging, the occupant was so ugly that she needed all the time she could get in there.
As for a 738 doing DRW-SYD and being too cramped, I shudder to think of the experience on AS with HNL-ANC in their 738.
