Really? That's going to be hard for a lot of us away in Asia for a week to do, especially on 10 hour duty days back of the clock in god knows what country.......yeah wonderful idea.....
Besides the obvious health and safety issues.
You are aware that in the ICAO medical manual it's written that Flight Crew should be given a hot meal every 4 hours, something to do with blood sugar levels, staying awake ( fatigue ) health and safety and all that poppy cock!!
So you just go ahead and grab a day old sandwich from that nice little chew and spew coffee shop next door to your comfy little office......if you get sick then just go home to bed ( or the toilet bowel )
