As as cc who has experienced the opposite of this situation in that I have been on a flight where a female passenger "interfered" with the gentleman sitting next to her who incidentally was travelling with his wife and 2 kids in full view of said gropping, there is no difference in my mind as to how this situation should be dealt with. If we worked as bouncers at a club then it somewhat goes with the territory but as "safety officers" onboard an aircraft we are entitled to go about our duties with out these incidents occuring. it is after all an offence to be intoxcxicated onboard an aircraft under UK air navigation laws.
