Let me answer from a personal experience as I do some professional freelancer photography from time to time (and what I mean by professional is "Paid").
The friendly manner and commitment (as long as you got the talent) guarantee you the loyalty, which means that client will not only hire you again for any coming event, but rather he will recommend you for his friends.
And the more events you shoot, the more experience you get, the more popular you will be.
If you live among a group of people in a certain area is characterized by certain characteristics may be special habit may be dominant in this region has a special character to live with only natives of this region
So ..
None will not know my requirement, and what I like about it as I used to see it ( i mean as i used to see how is it beauty ) only the person who lives in my area
The good maners with your clints and beeing friendly will enhance your chances with more clintes , it is your reputation as friendly and trusting person and will make you become the area famous photographer one day.
Thank you
