At Romanian weddings we give cash as a gift to the newlyweds. The usual amount is more than 100 euros per person, in order to cover twice the price of the food, drinks and entertainment spent per person.
Because of this, people hate it when they are invited to weddings, calling the wedding invitations “fines”, but they get even more upset when they are not invited.
One of the worst “crimes” you can commit in Romania is to not go the wedding of a person that attended your wedding, this way not returning the financial gift. This is why people keep the lists of people who were at their wedding and the amount of money gifted by the respective person, so they can return the exact favor when the time comes.
