I forgot to add that I am UK based. It is nigh on impossible to do these damn checks! I could spend my whole flight going from toilet A to Z, and still would not make the checks every 20 mins. Surely if a pax found a message/package/smoke, they would inform one of the crew? IF a package WAS found...What on earth can we do about it, apart from putting it up against door 5? It beggars belief, and drives me insane! We CANNOT be all things to all people..is there not a limit to our abilities?
