When working in a huge office

If one works in a Business Process Outsourcing facility, I wonder how many invitations will have to be printed and sent every time a major event transpires. Weddings for instance, are something that most brides consider very seriously and invites are surely sent to a lot of people. Unless the wedding will be done in a whirlwind manner in Vegas, I am definitely sure that brides will want to have that grand celebration. For those working in outsourcing facilities, how many invites have you received from co workers?
