i use to run the finance for a major chain of hotels. On bills they will charge the guest say 17.5 % service charge - that doesnt reach the person who say " serviced " you!! It goes to the hotels profits and a small percentage actually reaches the staff who deserve the money. best thing to do is take off the service charge from the bill ( you can do this its your right to decide wether to pay this or not) then pay the staff the service charge fee as a tip.

Much nicer option we should all tip out here its our duty to i believe most people earn very little out here and when you have little you would be amazed how far a little extra can go
