A very limited range of questions, on a very limited range of topics.
I have never been to a wedding where the bride and groom asked for money. I have been to ones where guests were asked to give money to a chosen charity rather than give presents. That way no-one knew how much anyone had given (if any), but the charity got a good sum of money.
I think this limited questionnaire was aimed at the big expensive showy wedding population. We are the church wedding with African choir and Performance Poet as the master of ceremonies in a village hall kind with catering and decorating done by friends. Perhaps Relate doesn't have much experience of those kind of weddings .
GN, though should know by now that the range of weddings people choose, cost and dress, do extend beyond dressing like a lampshade and spending too much money.
