The question makes the assumption that you believe that a sleeping passenger shouldn't be woken up to ask if they want something to drink. In F, if it makes a difference -- it's not like it will be half an hour before they can get one if they miss their first opportunity.

It's a 737 on a 2-hour flight departing at 5pm. About 5 mins after takeoff 2D falls asleep (and if it matters, she's apparently GS, judging from pre-flight activity detailed here) .

After the seatbelt sign comes off, the guy next to her goes to the lav, and the FA comes around taking drink orders, and wakes her up. They had an ensuing discussion about whether this was OK or not, and I definitely support the pax, but hypothetically:

If the FA started to wake up a sleeping pax next to you to offer them a drink, someone you didn't know, would you try to stop them?
