Way out of order.
I snore, and I'm happy for my wife to wake me up. But snoring isn't intentional and when you're sleeping you yourself are unaware. But I don't want to cause others annoyance. But that doesn't give carte blanche for anyone of a plane to wake me up. My preference would be for the complainant to speak to the cabin crew and ask them to wake me. If they haven't had training in how to deal with what must be a fairly common occurrence, or aren't prepared to wake the snorer then there's little that can be done. Touching another individual without good cause is a dangerous place to go.
