10% in Hotels etc.
1 or 2 riyals petrol
1 or 2 if car hop
5 if cleaning windscreen

5 or 10 for home delivery

BTW in hotels etc. I always ask who gets tips, if for the server alone or if pooled for staff ok

If confiscated by management for breakages etc., believe me it happens here...... Nothing!

Once in the Pearl I had to leave tip with the girl in the next door shop for the waitress as requested. Management took all tips for themselves!
