I believe it is "SOP" in a number of airlines for the cabin crew to supplement the remaining crewmember whilst the comfort break is taken...
Ooooooh-er! Fnar, fnar!
I find it hard to even get a response from the Cabin-call button these days. Too busy selling scratch cards and perfume to waste a few minutes in the flightdeck. If the SLF are second rate, where does it leave the Flightdeck?
Y'know, I'd Reeeeeeealy like to have a try on that door with the fireaxe. Just to see what it is like to try and get through. We use the tiny gap under the 757 door like the receiving end of a telex machine. Pieces of paper with "HELP! I Haven't had a cuppa for 2 hours!" get fed through. Then we sit and watch the spycam and see how long it takes before row 1 pax tell the C/S that it is there. Bugger-all else to do on a night Canaries flight.
