Traditionally, the father of the bride was responsible for the wedding banquet hosted on the bride's side and the alcohol consumed during both feasts.
The wedding banquets are two separate: the primary banquet is hosted once at the bride's side and the second banquet (smaller banquet) at the groom's side. While the wedding itself is often based on the couple's choices, the wedding banquets are a gesture of thanks and appreciation, to those that have raised the bride and groom (such as grandparents and uncles). It is also to ensure the relatives on each side meet the relatives on the other side.
Thus out of respect for the elders, wedding banquets are usually done formally and traditionally, which the older generation is thought to be more comfortable with. On the night of the wedding day, there was a custom in some places for relatives or friends to banter with the newlyweds.
