My FI comes from a polish family and of the few things he is insiting on at the wedding is a money/bride dance. (you pay to dance with the bride) Having been to countless of his family and friends weddings they have all done it and if we didn't it would seem odd, plus he wants to.
Was talking to my ma about any rough ideas we have about wedding/reception and told her about the dance. The poor woman was horrified.
She wants to tell my family about the dance before and apologise for it when they ask her about wedding registry (which will not exist)
Basically she is very worried about offending someone with the dance. Do we have to explain it to people? either on the day or as she wants to do when people ask about gifts inform them (though usually in FI family people pay only a dollar or so) as she is worried people will think the dance is the gift part or people think we are asking for (extra) money. Which we aren't at all.
