Paid for a Hotel Bill from my English Bank Account that was in Euros. Tourist Exchange rate was about 1.3 and the ffr at 1.4. The bill was settled in full from the English Account that the advance of pay for the payment of the bill was paid into. However i have now been audited 18 months down the line and i have to pay back an extra Â£50 as the hotel bill (Euros) was converted at the FFR at the time instead of what i actually paid from my account. Long and short of it, am i able to do anything about this or do i just lie back and take another one for the good and benefit of the army.
