Group of uni mates when we were in our early 30s
All lived in London, except for one couple who were staying with me for a weekend, so I offered to host dinner at mine and get everyone together. Everyone had about a month's notice
Got RSVPs from everyone except one couple, who ignored the original email and my chasing one. Fine, they don't want to come. No skin off my nose.
Everyone is due to arrive at 7:30pm, and DH and I had been cooking for several hours.
At 4pm, I got a call from a friend to say non-RSVPing couple had just texted her and said 'are you going to Spare's tonight? We are thinking of going'
To which she replied 'Err, I think you need to talk to spare about this'
I message them and ask if they are going to come. No reply.
Oh, and did I mention they are vegetarian?
Everyone arrives, we have drinks and serve the starter. Just as we are sitting down, the doorbell rings. They have arrived, absolutely arseholed... No explanation, no apology, no bottle of wine
We grab a couple of chairs and make space at the table, and DH wonder what the fuck we can serve them, given our meaty menu. They end up with some tinned soup as a starter, and I have to disappear back into the kitchen to make them a veggie main.
Over the course of the next hour, they spill red wine all over my carpet, the wife sets fire to her hair by leaning across the table and over a candle, and then sends the candle flying and gets wax everywhere.
The final straw was during the main course (beef) when the husband decides he isn't so vegetarian after all, and asks if he can try some... The wife then gets into a furious argument with him over it, and storms out of the house.
The husband then expected us to stop what we were doing and help him go and look for her.
Surprisingly, I have never seen them again since...
