I'm booked on a flight that leaves BKK at 00:30. (Bkk-zrh)

I'm assuming meal service will start around 1am. I'll be in f class and I was thinking that it's going to be really late for a 4-5 course meal. The meal service probably won't finish until well after 2am, at which point I'll be asleep in my meal.

What is your experience on flights that leave this late in regards to meal service? Is it quicker than normal? maybe smaller?
