Why do you charge extra for recording after 22:00?

We have found that we are mostly finished with recording by that time of night. Sometimes the Bride and Groom delay some of the formalities too late. We would prefer all formalities to be finished by 22:00 so that the BRIDAL COUPLE could enjoy the rest of their festivities . If we have captured all the formalities and function, we would like to create a nice ending to your DVD.
