I always implore my clients to have respect for your wedding vendors and service staff. It is of utmost importance as this can also affect the success of your event. It also affects your planners relationship with the vendor for future business after you are long gone. It is also important that your bridal party understands that they also represent you on this most important day and that they act accordingly. Recently I witnessed two members of a bridal party being rude to the service staff this was done right in front of the properties general manager. They had no idea who the person was and this affected the evening from here on out. There was no leniency from there on out in terms of going overtime, no leniency in coming back the next day to do shots.
So I implore no matter who you are, how much money you spent at the venue etc is also nice to treat the crew that work behind the scenes with dignity and respect.
