The wages are fairly low and so generous tipping is appreciated but not over the top (around 10-15%).

This a Muslim country and ladies especially must be careful about how much of themselves they reveal.  covered shoulders and upper arms recommended....Couples need to be careful about bodily contact in public, i.e:  none. Ladies will look and feel conspicuous in very light clothing, short skirts, shorts etc. 

No bare shoulders, short skirts or shorts or transparent clothing.
