It is really interesting reading over time about the different customs/expectations when it comes to weddings and receptions. Where I am from, the invitations were a formality. Everyone knew the details and everyone showed up at the church (if you wanted to attend). Receptions were in the hall attached to the church and were held immediately following the wedding, as in walk from the sanctuary into the hall. Receptions were cake, mints, nuts, maybe some other nibble, and punch (non-alcoholic since we were in a church), water, coffee. The reception usually lasted about 1.5 to 2 hours. So, the whole affair, including wedding, reception and send-off lasted maybe 2.5 to 3 hours, tops. Three hours would have been long.
