We paid $8 for the transaction.
There were 5 of us and the teller suggested we do the exchange in one transaction in order to pay only the one fee.
She also gave us 1 x 20 and 1 x 5 each to make things easier at the other end if we ended up in different queues.
It did make things easier and much quicker at the other end by paying in USD.
