Rubbish on dining table is OK

In some places, you will be fine dearly for littering on the roads etc.

However, in hawker center, coffee shop etc, people can "spit" bone etc out from their mouth onto the table, the cleaner will carry a cloth "mopping" the table, "mop" without cleansing the cloth as often as it is needed.

the mopping carry on from table to table, which mean spreading whatever food leftover (worse still germ from someone saliva) from table to table, a deer child will rest his cheek on the "cleaned" table while waiting for his food

I think there are ways to avoid the above but who really care?
