I think that if folk started doing this - and the idea is deliciously naughty - and most importantly gave it back to the crew - this could work as you say. What a wonderful wheeze! I would join in but truthfully I find BA's coffee awful and the tea not much better ( all my coffee comes from Meo or Carte Noire and the tea is Punjana. Mine I mean not theirs) Thus my tipple comes in a glass and so it has not affected me as much. It is ridiculous that this conversation is taking place - this should have been sorted out weeks ago.
