I don't think you lot are for real... are you?
When he says 70 to 100 a day he means a working day not every bleedin' day and only on a long haul trip. Now lets say you do 4 LH tripswith a 24 hour layover thats 400 us and for all the SH trips you do to plug the gaps you get diddly squat, no flight pay, no hardship allowance , no nothing in fact.
If it was 100 us just for dinner then fine but most of us like a little breakfast and perhaps some lunch and believe me if it's the hotel in Dhaka you won't get $100 nor in the UK hotels, you'll get 60 to 90 quid in the UK. OK if you like MacD but I'm a little past that. The money they give you will cover the food you buy or if you choose to spend it on liquid refreshment then that too but not both, so for the 340-200 man i think you're nearly on the same cash, maybe just a touch less.
