DXB to LHR in F last Friday night. 747. Old F.

German male who considered it appropriate to:

1. strip down to his undies in the cabin whilst still on the ground in DXB before departure, then sit in his seat contemplating a drink order with no trousers on (eventuually putting PJs on in the cabin); and

2. reply to every announcment made over the PA with some form of comment or retort.

Bizarre.
