Yeah my average cost lifestyle of course the odd extra as mentioned and wife takes care of herself.
I go by UK pounds averaging it out over 12 moths but 300 $ is about 10,000 baht by my calculations.
So I pay for house Electric, water, internet, mobile phone, fuel bikes, diesel truck, bikes/truck road/ins, evening meals, breakfast and midday sandwich, afternoon beer which averages out at 10,000 baht per month.
