The marriage license. This needs to be given to the best man on the day of the wedding.
Help with the purchasing of gifts for the best man and ushers.
Fees that need to be paid for the wedding ceremony.
Last being on time for the wedding and ready
Being involved in picking out the groom’s cake
The grooms cake has been a southern tradition. This cake is based upon the groom’s hobby, profession, and interest.
IF he likes fishing some couple have a made the cake into a shape of a fish or have a fish designed on the cake. Another man may love cars and he may choose to have a design of a car put on the cake .
One can really have fun and be unique on designing a groom's cake.
