Even if you can somehow improve the number of dishes the Dishwasher washes, the time taken for the cleaner to clean a table, do you think someone the Food Court stall management really cares if you are able to do it faster? I don't think so. Cost is more of a concern for them since no matter how fast U clean a table, there is only so many tables in the food court. And if everyone is forced to pay more due to a minimum wage system, they will just jack up the prices to maintain profits
==================================================================
If one cleaner can do all the cleaning up on his or her own fast enough , you can have more business turn around.The cleaner can also double up his job scope as dish washer. There is dish washing machine now. So we do not need people to physically wash the plates. Just need her to place the plates there.
Instead of using cheap labour, we can increase our productivity by using our kjnowledge and advantage. Thus, our total productivity goes up.Our current employer is being spoilt by the goverment themselves.
Just imagine, there is dish washing machine in Coffee shop. They can save so much money in long term. We shd not be competing on labour cost now. We shd be competing on technology and know edge to give all our counter part a run for their money.
Now it isnt abt cost. We are using technology to increase our productivity, thus bringing down the cost indirectly. Back to the question of wage, if i can hire someone who can run all my operation in one go through use of technology, i can naturally pay him or her better.
