Has anyone considered closing and or locking the doors to the venue a few minutes before their ceremony starts to keep stragglers from interrupting the ceremony? I think it is extremely rude for people to walk in at the last second or even during the ceremony. My only problem is deciding on how long before the ceremony should I do it? 5-10 minutes before it starts? 5-10 minutes after starting time? No one will be locked in or can't get out if there is an emergency , just to keep stragglers from interrupting.
