I think you, and a few other posters are this thread are very unreasonable.
Questions like "you went to Leicester for food?" Are great. Simple to answer in distress, and gives an indication of the side of the road the car is on
Slow calm voice, helps to get the information needed, without increasing stress
For those saying the handler should have said to pull over, you're hindsight really is 20/20 isn't it?! However, whose to say the two men wouldn't have left themselves even more exposed as sitting ducks if they had slowed down/pulled off the road. The handler doesn't know whether this is gang incident or whether the following cars have guns that will just shoot them instead
Increasingly we seems to be a society that automatically thinks everyone else is stupid and unwilling to think that they may be privy to information/knowledge we don't, or forgetting that we have the benefit of hindsight. Call handlers do a phenomenally difficult job and sniping over language is a shitty thing to do
