I work at a restaurant that has a decent bar scene on the weekends so we have bands and dancing and we card at the front door. A couple of years ago, I am managing on a Friday or Saturday night, and the band is going strong, people are dancing, and things are busy. I get called to the front door. The Door Guy (who checks everyone's ids) won't let several girls in because they are under age but they want to try to come in anyway. I tell them they can't, but they beg me and one of them says that she is supposed to get married at my restaurant on the back patio. I know nothing of this, and ask her to explain. It turns out that her and the groom just decided to show up and thought that they could get married randomly on the property. The groom was already inside (because he was over 21) and comes outside to meet the girls. He is at least 45 or 50, and she is younger than 21 because we can't let her inside!
The best part is that they end up getting married out front on the sidewalk by the ugly gas and water pipes. And they are married by the drummer, whose band is playing in my restaurant, while on his 15 minute break?!
Word of Advice: If you want to get married somewhere, you might want to call to ask if its ok, and to make sure that you can actually step foot onto the property. Just a couple hours of planning might have done them some good.
