AITH For Leaving This Customer

Me and my husband both work 2 jobs. He works at Walmart and does door dash. I work as CNA and also do party entertainment stuff with my friend. It's actually her business but I go with her or go in her place if something comes up. She sent one of her clients over to me for a birthday party. He told me it was for her niece and she wanted to see Snow White. I said okay. I came today for the party and I notice no one is at this party. I go in and I meet the guy and there's a grown women dressed like a child. I thought "Oh special needs" but they started acting weird and she called him daddy and it became clear this is an age play thing. I wasn't prepaid anyway so I said I am sorry but I do not feel comfortable being apart of this. I am not judging people for their kinks. Do what you want if it's consensual. I also don't judge if adults want to see me. But to lie to get me to be a part of a kink without my consent I find gross. My friend wasn't even mad and she blocked the guy and found his girlfriend and blocked her for just in case.
