I'm a wedding planner, and agreed to do my best friend's wedding. Holy FUCK what a ride! His mother is a raging alcoholic but seemed to be keeping it in order on the day and all was going well.
The pair had forbidden anything stronger than champagne to even be present at the reception, due to this woman. And I made sure that SHE was specifically singled out to every caterer on the premises not to let her have even that, by couple's request. Nobody, not food caterers, not the bartender, was to put anything harder than Martinelli's sparkling apple cider into this woman's hand.
If she threw a fit at them, they were to come to me and I would take the nutjob by the ear and throw her out of the wedding entirely. The wedding couple told me flat out that throwing mom out of the wedding for the tiniest infraction was perfectly acceptable, and Momzilla was fully aware that we had that authority. We thought this would minimize fuss. We forgot one little detail...
Halfway through the reception, we hear a ruckus and notice the bride (a lovely Japanese girl he'd met through work) was nowhere to be seen.
People scatter to try to find the bride. We find out that she's locked herself in the toilet, in tears. She's so distraught that it took some cajoling from her to-be-hubby at the door for almost half an hour before we could get the story out of her in some coherent form.
Turns out the mother of the groom had SNUCK in something in... something that was almost identical to jet fuel in composition if the smell was any indication, and had then launched into a verbal racist tirade at her accusing her of 'stealing her son,' and 'doing it to get a passport,' (despite the fact the bride was already a British citizen and had been for a few years before she even met her hubby...) and all sorts of other horrible things.
I've never seen a grown man punch out his own mother in public, and never before have a seen a person so deserve it. Surprised the shit out of me as he was such a placid guy, normally. We all have our limit, I suppose. I don't know the details of what was going on in the run up to the big day, but this seems to have been the last straw.
Anyway, she was immediately ejected from the wedding, and as far as I know now (it's a topic we know to avoid) she no longer has any contact with them.
It's sad really: she was afraid of losing her son, yet she was the cause of it.
