I'm getting ready to do some cake tastings, so I've been researching things to ask the bakery, etc. In the process I've come across several mentions that traditionally the cake cutting is a signal for elderly guests to depart the reception. What?? Is there some sort of history/symbolism to this? Is this something that people really do? I would like all of my guests to stay and enjoy a slice of cake, if they are so inclined. I also wouldn't begrudge anyone who wanted/needed to leave early. I just don't want anyone to feel they need to leave because we're cutting into the cake.
