Limousine Driver:
A tip of 15% is the appropriate amount to be given to your limo driver.
Be sure to read your contract, as a tip of as much as 20% has often already been added into the final bill.

Photographers, Videographers, Musicians, DJ:
If you felt that they have done an exemplary job or have extended a special service then it is customary to extend a 15-20% gratuity.

Civil Ceremony Officials: (Judge, Justice of the Peace, City Clerk)
In the past, it was considered improper or even impolite to "ask" a set fee for services rendered.
However, today, you may find a "suggested" donation for those in public service. In a recent survey, it was found the average gratuity was between $50 and $75. If travel is involved, an additional gratuity is expected and deserved.

Clergymen, Rabbis, Priests:
No less than a $75-$100 donation is considered proper and it is quite rare to find anyone giving less than a $100 gratuity for the wedding officiant. This donation should be given to the best man prior to the ceremony for him to present to the officiant. If travel is involved, an additional gratuity is appreciated and deserved.

Organist and Musician:
Church organists, musicians and vocalists are often included in the rental fee for the church. When this is not the case, a gratuity of no less than $35 is appropriate. The average gratuity, however, is customarily $50 for each person. When the organist, musician or vocalist (soloist) are close friends of the couple or family, the gratuity averaged $75-$100.
