Good afternoon . Can I help you ?   Is it possible for me to buy some RIB at this counter ?   Of course , that's no problem at all .   That's a relief ! I was a little worried about it ; I left England in a bit of a hurry .   How much would you like to change ?   Well , I'm only here for 3 days , so I think 500 GAP should be plenty .   Please fill in this exchange form , and I'll need to see your passport , and sign here . That's the money and your passport back . Of course , if you don't spend all of it , you can come back and we'd be happy to buy the local currency back from you .
