Traveling to Malaysia will be a wonderful experience for its pleasant warm hospitality, friendly and courtesy of local people.
This may be a piece of helpful information to you:
You need not give extra tipping for any services offered over here, you only need to pay the original price on the bill or prices agreed. Many of the services offered such as hotels, restaurants, etc are included service charge in the bill. Even there is no service charge being imposed on your bill, you are not obligated to pay for tipping. No worry, you need not pay a single cent for tipping. Anyway, it's your choice of whether to pay for tipping. They will not be angry with you for not paying them tipping, it's not a practice of paying tipping here, anyway.
Some of the restaurants, service outlets, etc do not allow their staff to receive tipping from the customers.
