Men greeting Women - Greetings depend on whether the two people are religious or not. Those who are religious do not shake hands at all or make eye contact with members of the opposite sex when in public . They maintain distance, especially if they are not related. If they have to greet one another, a slight bow is made and some distance is kept; 3 feet apart or more. In other situations, a nod of acknowledgment will suffice. Handshakes may be common in certain situations, but it is always best to wait and see what action the person you are greeting takes.
Note: It is taboo for religiously observant men to touch women and vice-versa.
