Today I learnt, that when we dine in restaurants, we have to give tips.
(Well, I've always knew, but I didn't know how much exactly I'd have to give)
So here goes, some standard practise:
15% from your total spending - for an OK service
20% from your total spending - for an excellent service *two thumbs up*
So yeah, the waitress/waitresses would be expecting you to give tips, and even when you pay with your debit/credit card, they would return back the receipt to you together with a note on how much tips you want to give, and you should probably give cash as tips.
That, or you buat-buat bodoh je lah and walk away without giving anything.
HA HA HA!
