Hi Malak - when we eat out if the service charge is included we dont leave extra tips unless we have had exceptional meal and service. We tend to tip at the end and give to our favourite hotel waiters and barman. I also tip the pool guys every couple of days and if one has gone out of the way for us we would give him extra on our last day as a thankyou. The cleaners also get our small notes at the end of our stay and one of the kids normally arranges all the money in the shape of a flower, heart or something on the bed! They also get our toiletries that are half full as well.
