and just after TOD the plonkers started to dial their mobiles phones telling their relatives that we are going to be 5 minutes and so on,
That might explain why the chap in the seat in front of me started using his mobile as we were taxiing out at SFO a couple of months ago. Telling the relatives he was about to take off. The woman across the aisle from him managed to get him to stop about the time I realised what he was doing and before I could signal the cabin crew. If it's normal practice where he lives then he obviously ignored the "please turn your mobile phones off" annoucement that had taken place a short time previously.
