Off topic, but talking of carry-ons and sandwiches:
Two weeks ago I went to Brussels Club class from Heathrow. There were cabin crew, also in Club, positioning.
Most of them were over the published carry on limit.
All the cabin crew were on the RHS with an empty seat between them. The club passengers were on the LHS, seats adjoining (it's 2 x 3).
After take off, they came round with sandwiches. The purser / CSD (call it what you will) went down the RHS of the club class section, and served the cabin crew first. All the cabin crew got their first choice. When he started working back (serving the passengers) there was no choice left. Same sequence with the drinks.
There was turbulence during the flight, and the light came on. One of the positioning cabin crew stayed standing in the galley chatting with a mate. When the light had been on about 15 minutes, one of the positioning stewardesses got up and went to the toilet.
Now, if I say something I'm rude, unreasonable and a troublemaker (however mild my manner). But why should I be expected to put up with it?
