I withdrew cash for my GBP account for old man over Christmas 2015-2016 in GBP and Euro on our family holiday.
I want money back in AUD, which is what he would have withdrew in.
I use the word "withdrew" in the first sentence rather than "loaned" as it was a convenience thing and he could have paid me back the next day (imo). He has been trying to pay me back, however I have only just got back in to him with the total amount.
Should I
A. Be repaid as per current exchange rates
B. Be repaid as per spot exchange rates at the time of withdrawal
C. Sort it out with "old man"
