Not me.. a friend, attending her employers wedding...
Tried very politely to deal with employers Dads wife, who was getting steadily more and more sloshed and as she did so, more and more determined to chat up and attempt to snog friend.
Thinking she'd given the letcherous Step Mother the slip, she went to the bar, where employers Dad grabs her by the back of her suit, hauled her out into the car park and thumped her for trying to get off with his missus!
Full on yelling match, people holding him (fairly big) back from trying to beat up a 5ft 3" 40 ish lesbian, accusing her of having an affair with his wife (she'd seen her in passing twice over the course of her employment, sufficient to know who she was but not what she was like at parties!), he was going to hunt her down and all sorts of ridiculous and horribly aggressive shit.
The next morning, she had five missed calls, a load of grovelling voice mail apologies, and an envelope through the door with a 'sorry' card and several hundred quid in notes. Her boss, when he finally found out about it was absolutely mortified, horrified, hugely embarrassed and deeply apologetic!
I was shocked she let it go tbh, but she does like working for him and felt reporting his Dad to the police wasn't the way to keep a lucrative job!
Only wedding I went to as a kid, friend of our family... his ex wife walked in at the 'does anyone know any reason why blah blah blah' bit in the church and screeched 'because he's a creep and she's a slag' and then crashed out through the doors chased by several people. She bricked a car she thought was his (she must have been absolutely trollied as it was some random strangers car of a similar shape/colour, they'd both arrived in taxis!) and was then arrested for that.
