Perhaps they are - I'm not one of them. But we do have some ethnic minorities who are also veggie. That's the main problem - an extremely wide social mix of people which makes pleasing even the majority hard. Rich/poor; local/western palate; veggie/non-veggie etc etc. Anyway. Enough of this - I'm going to give up trying to "help" shortly (the organiser of this might not necessarily be appreciating my "help"!) although I have offered to get him a room at the Gold Coast Country Club - we could easily do something for the budget there but would anyone come that far out?! (you don't need to answer that).
Not helping with your problem moving but one thing we do here in the office when we go out together and to somehow ease this income difference issue is split the bill by "seniority"/
Say the bill is HKD 10.000 for 20 people:
Managing Director/Executive Diretcor will pay 1000 (Assume they are 4 that's 4K)
Director/VP will pay 500 (assume they are 6, that's 3K)
Associate/Analyst will pay 300 (assume they are 10, that's 3K)
I am making up the numbers, but you get the idea..
yeah, or take skin colour, white: insert here ^^
or distance from place of origin; if they can afford the ticket they should pay more for the food !
