I am disappointed over the problems arising from the latest parking coupon exchange ("New parking coupon respite - but just once"; Dec 8).

A number of petrol stations and shops have been reported to be out of stock for the new parking coupons.

A common sight in carparks now is drivers asking other drivers for parking coupons.

Despite the lack of new parking coupons, car owners face fines for not displaying their parking coupons or for displaying the old coupons.

The authorities should have anticipated such an issue, which is harmful to Singapore's reputation for efficiency.

Surely we can do much better.

The relevant agencies must respond to the issue and present the actions they will take to address the problems.
