Thoughts on passing a parking meter

Ambling along on the pavement on Galle Road, Wellawatte, I paused to study the new parking meters that are being installed. Here’s what I saw:

Exact Change- No RefundsCharge for cars Rs 30 per hour. There are no place to insert coins on the meter. Now how is one to deposit Rs 30 without a ten rupee coin? There are no ten Rupee notes any more.

Or is one to deposit Rs 40 and forfeit Rs 10 on every occasion? Nihal Ratnayake
