Nature Gonna Nature

One I remember was a woman who was very sweet up until after her wedding. We had to substitute peonies (every bride and their grandma's favorite flower) because they weren't in season and to get them she would need to pay a ton, so she opted for garden roses instead.
It rained on her wedding day, not like "maybe we should make a rain call", like tornado sirens and shit falling over. The power went out and the hotel used all of their backup generators to light her ceremony and reception for the 3 hours the power was out. The rest of their guests just had to be rich by candlelight I guess.
None of that was her fault, but none was ours or the hotel's either. Nature gonna nature. She tried to sue not only us for "fucking up her bouquet" but also the hotel for not letting her ceremony be outside and for not letting her ceremony be in "the prettiest area" of the inside of the hotel.
Thankfully we always have 2 coordinators meet with brides from this venue (it's our biggest client) but we also record consultations and have contracts notifying all parties. So she couldn't do shit to us but she did decide to blast us on yelp, facebook, and any other social media medium she could. Thankfully we threatened to sue her back for defamation and she removed them all.
The hotel has similar practices but also a ton of money to throw against her in court so they basically told her to bring it and she backed off.
More recently, not involved with us directly. A groom from a wedding we just did is claiming the venue they used stole from them because he didn't receive wedding presents from all of his guests and he's 100% certain every single one brought them something (they requested money by the way, only money). So now he's wanting to sue the venue while also calling all of his guests to make sure they gave him money for his wedding gift. This one is more fun to watch burn.
