Thanks for all the PA's guys, i have noted them and will be using them on a regular basis and its my one pet hate on baord (that and when u offer sumone coffe from ur pot they insist on putting their cup on ur tray asking for tea!! ITS NOT A MAGIC POT!!)
I have to say, the Italians are worse for standing up, i have done many flights from Milan and the minute the back wheels touch the ground they r in the lockers, on the phone, wanting to use the loo!!
