If you are absolutely not satisfied with the service you got (or lack there of) from Nepal Embassy, send a letter saying so to the Foreign Ministry and as many newspapers as you can.  Dignified service is your right, not privilege.  You have the right as a Nepali citizen to be treated fairly, competently, expeditiously and with utmost dignity from the staff of your embassy.  After all, those people in the embassy work for you.  Their very existence is to provide service, among other things, to you, Nepalis in America.  Don't let yourself be cheated out of what is rightfully yours.  Even more, don't let them continue to cheat others with impunity.

And name names.  Make them accountable.  Do not generalize and say that the staff at Nepalis Embassy are jhoor.  Say who is jhoor, when was he jhoor and why was he jhoor.  State your issue credibly, i.e. do not embark on name calling and being unprofessional in your accusation.  Be very matter-of-fact, without being overly emotional.  For example, the clerk you mentioned is not Dick Tamang.  His name is Dig Bahadur Tamang.  If you feel that he did not provide you good service, as he should becuase his salary comes from Nepali people's taxes, then tell the ministry and the media about him.  But do so in a professional manner.

My dui paisa.
