People being late makes me anxious and uncomfortable. I hated the idea of people being late to my wedding because i knew i would be ready early. Even if i try to be late i just end up being early somehow. DH bless him rang around everyone before the wedding without my knowledge to say please be early and explained why.
Then i was in doing the pre-wedding interview and (i didnt know at the time) a couple turned up and the woman was desperate for the loo. DH told her she could either "watch or wizz"... she chose to wizz and he told the venue not to let her back in or near me. She was his guest thankfully. Its the couples day and its 20 bloody minutes. If you dont care enough about them to respect the request then dont go.
Glad this is your husband and not mine.
To refuse a person entry to your wedding, because they needed the loo as soon as they got there is appalling behaviour. What a way to treat people. I would be so ashamed and embarrassed.
If these people are so awful, and sooooo annoying because they are always late, then why the hell did you invite them to your wedding?
Did you just want to make a point? Did you want to shame them? Did it make your husband feel like a big important man? And did he puff out his big old chest and beat it? 
Whatever the case, treating those people that way was disgusting.
Yes he did and i bloody love him for it. They were his guests. Theyre always late for everything. He specifically asked them to be early. He knew i was around and that she would take ages faffing around as she always does so told her where to go. We got married in a building with a beautiful public park so my FIL (DH best man) gave her a fiver and told her to grab a coffee and we would be done soon.
WOW. Words fail me. 'Here's a fiver, now piss off and get a coffee and come back when the grown-ups are done, seeing as you can't hold your bladder for an hour til the ceremony has finished.' 
After the wedding, she sincerely apologised saying she hadnt realised i would be "that on time". Also, she hadnt travelled, we got married in our home town and she walked to the venue!
Oh so this is a valid reason to treat people like crap then because she hadn't travelled and had walked to the venue (If that is actually true.) 
And she probably 'apologised' because she was embarrassed and ashamed. It sounds like you and your husband are very happy that you made her feel that way.
How proud you both must be.
