New parking meters

Ambling along the pavement on Galle Road, Wellawatte I paused to study the new parking meters that are being installed and here is what I saw:

Exact Change – No Refunds – Charge for Cars Rs. 30 per hour.

There is 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 anymore.)

Or is he to deposit Rs. 40 and forfeit Rs. 10 on every occasion.
