411a - I like that post!!!!!
You should, but not perhaps for the reasons you think.
Years ago, I flew for a quite small asian carrier (of course, thay aren't small anymore, in fact they are now the largest) and the CC used to either purchase locally out of a grubby stall or...bring from base, their grub, and cook in one of the CC rooms.
All fine and dandy until one day they invited myself and our First Officer to 'dine alFresco'...I declined, preferring a steak in the hotel restaurant, but...the First Officer (a superb guy by the way) accepted the invite, and for his acceptance came down with a case of hepatitis B...and was off flying for no less that six months.
Certainly not a pleasant experience, as you might imagine.
Now, imagine this happening in LOS...well, you get the picture I'm sure.
