Lol, true, the GAF factor seems to be decreasing a lot lately... inducing many
moments for quite a few of us...
See now that would be an ideal solution except you forget it probably doesn't make much difference since many of our pax seem to see the s/b sign coming on as a flashing "Go Pee Now" sign and it takes longer to get them sitting down again (unless of course you are me and just keep knocking on the door til they come out of the lav shame faced, seems to work a trick to tell them we can't land til they do and they are making everyone else late
)
