I used to use a website called Lang-8. It’s not really for direct chats, but you write an entry and then natives can come and correct it for grammar and/or natural feel. I was never brave enough to do full on chats with natives, so that’s the best I have ^^;
I live near a restaurant that has a sign on the side of the building that shows a zoomed in pair of eyes. Below the eyes it says “Fine, dine here!” as if the sign is just being passive aggressive and your patronage to the restaurant is really a nuisance. It’s so dumb, but every time I see it I can’t help but giggle!
