this happened to my mother-in-law, where she was the crasher.

in North London there is a large Turkish centre that hosts Turkish weddings. She was invited to a wedding there.

Traditionally, the bride and groom stand in the centre of the room and then family members lineup next to them all in a procession.

As you enter the room to reach the bride and groom, you must shake the hands in turn of all of the people in the procession.

When my mother-in-law eventually got to the bride and groom, they realised that the bride and groom were strangers. The accurate wedding was taking place upstairs at the same time.

There are multiple wedding venues in that particular Turkish Centre.
