Bubble tea CIP

This week my school's Red Cross is selling bubble tea at my canteen! I helped out, and soon we realised that there was a big problem. Because the bubble tea's cost was $1.50 each, we needed tonnes of 50 cent coins because people would usully pay in $2 notes! Hahaha... then I had to run to another stall to exchange coins while the queue was forming at our stall. By the way, we were raising funds. It was a good experience and a fun way to get CIP points!
