Well, Debbie Downer, people seem to like them and it doesn't take any of your focus; if it is profitable enough to run, you put an assistant on it. It is gimmicky but so are a lot of things at receptions. I've never run one at a wedding but I've set them up at my own parties and they are lots of fun. At a reception you obviously get guests being goofballs to make the B&G laugh at the photos later on.
If you're not running it... it makes money... and both guests and clients like it... why not?
"Debbie Downer." I love SNL references.
