why we dont clear own dishes

Clear my dirty dishes? But it's the cleaners' job
Food court fails in its drive to get patrons to clear their trays and used crockery
By Elizabeth Wilmot
DINE AND DASH: After eating, most patrons just left their trays and used crockery behind.
AN EFFORT to get patrons at a food court to return their trays has had dismal results so far.
Launched two weeks ago, the Tray Return Movement at Suntec City's Fountain Food Terrace has left one of its organisers disappointed.
The drive was spearheaded by Chesterton International Property Consultants, a subsidiary of Suntec Investment, which owns the food court. It is supported by the Singapore Kindness Movement.
So far, though, little has changed.
Many customers still do not bother to return their trays, leaving cleaners with more work and inconveniencing other diners.

'It's not easy. There are a lot of problems because people's habits do not change overnight.'
When asked why they did not return their trays, customers offered a variety of reasons. Some said it was the cleaners' job, others put it down to force of habit.
'Honestly, I did not think of returning the tray,' said Ms Joana Lim, 25, a financial consultant. 'Maybe bigger signs might help.'
Chesterton's Mr Sim said he was not really surprised by such behaviour.
'Good habits have to be inculcated in people when they are young. As adults, the habit of not returning the trays has become a fixed mindset in them,' he said.
