I once started a thread here about 'please let me sleep!'
I fly a lot of leisure routes for work and often seem to be seated next to the person who is on their first flight in 20 years, and for whom the beverage service and bag of pretzels appears to be a great novelty - they think that it is worth shaking me awake.
Not even a meal in LH C is worth shaking me awake for. It was actually suggested here that I enlist my seatmate as 'protection' ie request politely that they ensure that I am not awoken during my flight.
So, no, please do not wake me for beverage service. And like PTravel, I request that cabin crew are not unduly noisy. I recently had a run in with a LH purser in C, who was giggling and laughing with her friends/passengers and awoke me midway through a long haul flight. She did not appreciate it when I ran into her in the galley and told her that it was inappropriate to awaken sleeping passengers with her antics.
