We've had a few lousy experiences.
We've had people claim to be late 40s in their profile and be at least 70 when we met them, and of course people who were 30-75 lb heavier than they were billed as.
We've had people show up looking like they haven't showered or brushed their teeth, changed from work clothes, and the like. We even had one couple meet us at a restaurant and order nothing but water, leaving us to - alone - order things to justify our occupation of a table, and one who harassed us for weeks for not wanting to go play when they showed up looking like they just rolled out of bed.
Yet another presented well when we met (but didn't play) at a party, but they invited us over to their place and everything was a disaster. They were dressed like slobs, unshowered, their place was filthy and they had kids up and around. Uh, yeah no. We gotta go.
The guy's nasty behavior is something we haven't seen that much of. The closest was this rather attractive couple who otherwise might have been a decent fit, but he began bragging about how he beats up everyone who bothers him in the slightest. I don't know if this was just bravado or if he really does punch people who say or do anything he dislikes, but either way we don't want to get mixed up with someone like that.
Sorry about your lousy experience.
