orh.......maybe they busy lah. and then tipping is shared,
right?
over here, the wait staff get their own tips. that means ah, if
person A serves your table right, you cannot ask person B for help.
anyways, even if you do, person B will direct to person A lah. so
at the end of your meal, only person A gets your tip. and tipping
is sort of must. min. 10% before taxes.
like you go out to eat right? say bill is 100 and then plus 15%
tax, you got to pay 115. but you tip base on 100 and not 115. so,
say you tip 10% which is $10. so, in total, a $100 meal cost you
$125. jia lat hor?
