Well, Melissa of MasterPiece Weddings has, in the past year, utilized her notary public license at least a handful of times. In one case, the bride and groom's minister became unavailable at the last minute. Lucky for them, with MasterPiece Weddings coordinating things Melissa was able to step in and preside over the ceremony while I [with an assistant, of course] lined up and oversaw the processional.
In another case, the bride was so nervous that she decided being legally married ahead of time would relieve the stress. She and the groom-to-be arranged to meet Melissa mid-week, in her office, where Melissa said a few words, signed the paperwork, and sealed the deal.
Regardless of the situation, it's safe to say that as a wedding consultant Melissa has made use of her license far more often than she thought she would. While having a notary public license is far from required [or even expected!] in the wedding consulting world, it certainly acts as a cushion and a nice trick up your sleeve.
