I did some waitering job before, and ppl in Sg DO tip. Its just
not very widespread. And most of the time, the manager or senior
staff swallow the tip money and it does not get filtered down to
the newer junior staff and part time staff.
So your advantages of tipping probably does not extend to most of
the waiters and waitresses since most are part time.
Another thing is that, once tipping is implemented, it becomes
expected. Its no longer an incentive but mandatory, and if you
refuse to comply, expect them to show you the meaning of
disgruntled behaviour.
Do you notice whenever you go on tours overseas, at the end of the
tour, the tour guide will collect tips for the driver? A friend of
mine went on a tour to Korea, bt upon reaching there, his wife fell
sick and had to stay in the hotel thru out the holiday, with him
with her. Therefore, other than the trip to the hotel and the
airport, they never sat the tour bus to go anywhere else. They even
had to find their own way to a clinic for medical consultation. At
the end of it, the driver still demanded tips from them.
Right now you assume that you can give tips only when the service
is good, but how sure are you that this policy won't be
abused?
For wedding dinners, it is usually the custom to give tips to the
staff of restaurant. At the end of the one I attended, they had the
cheek to approach the groom and give him an empty red packet and
tell him that tips is 20% of the dinner cost. Their service was
rather bad and they even forgot the roasted pig!
Perhaps we can find other means to improve our service quality
rather than tips?
