Playing it safe (see below) I spent more time than usual in the toilet on the flight over. I was amused by the red button. Continental really did think of everything. I mean, imagine you're on the john reading the paper and you realise you forgot your gin and tonic. Not to worry, push the red button and a bald bloke will bring you a drink.
The lit up sign next to it comes on when the seatbelt sign lights in the main cabin (obviously they don't have seatbelts in the toilet). I thought it looked like he wasn't quite finished. Not sure how I got that from a stick figure - it just doesn't look like a confident stride to me.
