WOTC - Cleaning and dishwashing

I asked this question in the Wisdom of the Crowd:

NEA will provide subsidy to stalls for cleaning and dishwashing cost 

Here are the responses: (70 Votes)

39 % - NEA should ensure that the costs are obtained through open competitive tender and charged fairly to stall holders, without a profit margin.
37 % - Let the stalls handle their own dishwashing.
17 % - NEA should set a fair rate for dishwashing cost, based on experience of many hawker centers.
7 % - This is a good measure.
