I will stop complaining about mine. You're going back to that voluntarily? That must be some mighty mighty overtime pay. 
Well, it's only for 2 months this time

. Plus, you're working, sleeping and socialising so much that there's not that much time to go online anyway.
In terms of the money, it is certainly an incentive, because I earn about double my normal salary while I'm there, and my room and board is paid for by work. When I was renting I just moved out of my UK house while I was away and put my things in storage, so I could save almost my entire salary... I did 8 months overseas (5 in the Falklands and 3 in Ascension) in 2013/2014 and came home with enough for a house deposit.
Of course, now that I've bought a house, I have mortgage/insurance/bills to pay while I'm away, so I can't save as much as I used to be able to, but it's still more than when I'm in the UK.
Oh, wow... I would faint. Who paid for it?
The boss did!
I suggested to him that perhaps people hadn't turned off their automatic updates on their phones/laptops/tablets, and that was why we had used to much data (which happened to a colleague in Ascension... when she arrived, she had 4GB left of her 6GB monthly allowance and she used it all up in 2 days because her laptop was set to automatically update and kept downloading them). Not sure if that was actually the case, or if they were just deliberately ignoring the warning not to use the internet, but he seemed to accept that reason.
