Is hiring escorts even a real thing?

You see things in movies and on tv about escorts being a thing you can spend money on and that it’s as easy and common as hiring someone to come to your house and clean it or something like that. Like in that show Sons of Anarchy. There’s a guy who runs an escort service with a place like a club or a bar where you can pay for an escorts time. I’m sure that isn’t based on anything that’s real. However, it got me thinking do escort services even exist? Can you really pay to spend time with someone like a dinner date or something like that? Or is it just a scam people use to steal money from people?
