At my dinner party I refused to accommodate a guests “eating disorder” and they started a smear campaign against me.

I was hosting my christmas party last year and one of the guests brought up how he couldn’t eat anything with seemingly random combinations of ingredients that are too tasty. He specifically gave me the example of how he couldn’t eat chicken wings with honey as it’s the thing that repulses him the most. I though this was some stupid joke and when he was gone for a second I asked his girlfriend if he was actually messing with me and she said he actually had a serious disorder. When he came back I offered him chicken wings with honey. He went apeshit and said how he can’t eat anything I’ve prepared in that case. I told him I’m not making anything else and if he had a real disorder I’d accommodate him but since he doesn’t, fuck off. Him and his gf left and now he’s telling everyone I’m a shitty host who doesn’t accommodate his eating disorder. I don’t really give a crap that he’s slandering me I just wish I could tell everyone that he simply doesn’t like certain foods and lies about how he has an eating disorder.
