Despite the Keep Public Toilets Clean campaign and initiatives by the World Toilet Organisation, the state of cleanliness in many of our public toilets still leaves much to be desired ("Eat, drink but maybe give the toilet a miss"; Nov 15).

Among the usual gripes are wet floors, strewn tissue and toilet paper, dirty sinks with food particles and people not flushing after use.

In order to instil social responsibility on owners of food establishments, the authorities may wish to consider holding an annual "Clean Toilets Day". At the same time, the dirtiest public toilet in Singapore should be highlighted.

Hawker centres managed by the National Environment Agency charge members of the public for the use of the toilets, but these toilets are not much cleaner.

As coffee shops, foodcourts and MRT stations do not impose such charges, I see no reason why we should pay to use toilets in hawker centres.

Ultimately, everyone should play a part to keep toilets clean and make cleaners' jobs easier.
