A classic ploy to immediately grab a cloth and feel you up! Did she?
A really old French lady (who incidentally also needed help with her tv screen)... nah I don't even think she noticed as she was too busy cleaning up the coffee all over her tray table.
Incidentally that was the second really old woman I had to help out with screen selections. The first one was on the Dubai -> Lisbon flight who I had to help out about half a dozen times since she never seemed to learn from the previous experience. Woman #2 not only had glasses but also needed this massive magnifier to see what she was reading. Obviously the glasses weren't much use to her. At least she didn't spill it on me while I was asleep.
Its a pretty stupid "ploy" to spill boiling hot coffee on the crotch of a guy you like! If you like them then you don't want that part to be damaged or out of order due to burns. Cold water or soft drink is much a much better choice. :)
