Change Exchange

So, people want flavoured water and sometimes don’t have coins. This little experiment allows for people to swap notes with change. This is also based on an honesty system, if some money disappears so will the exchange.

Testing with $10 at the moment. Located on the wall in the Hipster lounge.

EDIT: Decided to change to $20 because $10 changes rather quick. Got $2 coins there now.

$5: 2
$10: 0
