Modern Libyans adhere to the tradition of Muslim society which revolves around the family life. a visitor's overall impression of Libya is one of modest amount of material comfort but with none of the flashy wealth of some oil-rich countries. as a result there is none of the general hassle towards tourists that you find in other north Africa or middle-east countries, for example locals begging for money, or hustling you to buy something during the visits of Souks or markets.
in fact an offer of payment for small kindness would probably cause offence to a Libyan. Also haggling over prices in markets in not common in Libya.
Libyans are very friendly to tourists but it is best to dress conservatively, for example short skirt and tight tops should be avoided, trousers, long shorts for both sexes will be okay, and ladies should cover their heads when visiting the mosques.
