Guys & Gals (... 'guts in particular)
Absolute bollocks with respect to cost of a Cuppa in Tokyo (eg at Startbucks etc).
In fact, if you don't mind filtered black coffee, go to Mr Donuts and it's a bottomless cup - If my memory serves me correct, the first one costs about 210 yen and then free top ups from then on.
My personal favourite is Doutour Coffee Shops where there is a wide selection of pastries, cakes, donuts etc plus Espresso Coffee. Well worth a visit if your ever in Japan.
Providing you are happy to eat local food (why you would not I can't fathom) the cost of eating out is not too bad. It is certainly affordable given the salaries and allownaces paid.
As for the training - just go with the flow. Your salary will be paid on time and providing you do what you are told, turn up on time and wear your uniform, everybody will be happy.
Cheers,
Fark!
