In reality, when it is heard that the couple are preparing for the wedding, some friends who have a good relationship, are careless or have ideas about their on-site ability will take the initiative to discuss with the couple to preside over the wedding for free, which is also a blessing and witness to the couple. If the other person is not a professional wedding master, try to politely refuse. Because of their lack of experience and enthusiasm, they often can't drive the audience at the wedding scene, and they can't improvise when they encounter unexpected situations.
