The Tube (Sky Travel)

IIRC the driver doesn't actually have to interact with the public much, he makes the odd announcement or two, but yes a driver will always get the odd complainer but it's nothing noone can handle, you just stay calm and give them the details.

Although I think it should be a real driver making this statement , not me

We actually interact quite a lot!

For example; waiting on the platform to pick up, changing ends, answering those who can't read the destination (esp Earls Ct), when tipping out (ie, Barking) and at interchanges.

Of course there's also the disruptions, which is when we don't want to chat with customers. Now I don't mean that in a rude way - here's an example:
Yesterday, i'd been at Embankment (Eastbound) for around 5 mins being held at a red signal and getting no joy from the train radio. Out of the blue, the platform PA comes to life with an announcement that there's a security alert at Blackfriars, and that my train is being held for an indefinite period. At last the train radio comes to life - 'driver, tip out and reverse back west, i've got trains in tunnels that need to get to platforms'. By now it's been about 8 mins, so I try to get a move on as, by the time I complete the move to allow other trains access to stations we'll be looking at a good 15 min delay. Don't forget, i'm tipping out at Embankment with plenty of 'foreigners' and loads of questions. Station staff? Don't be silly!!
So in this scenario - I need to get my train moved as quickly as possible, so that trains stuck in (warm) tunnels can get their passengers to stations. Interaction on this occasion was a pain in the rear!!
