So I went to use a restroom at the mall today. I was washing my hands when I started hearing odd noises so I closed the tap and I'm like "Where the fuck is that noise coming from?"

Some people were having sex is the stall behind me. I'm not sure if they were trying to be discreet but the girl kept moaning and the guy kept trying to shush her. Anyways, like Kermit the frog, I know it's none of my damn business so I dry my hands and leave. Shortly after I see the guy and blonde chick walking out and looking awkwardly at me and grinning from ear to ear. The guy nods at me and I nod back. Respect bro.😄

Are hookups like this common or just a rarity? I've heard of drunk people hooking up like this at parties and clubs but I've never experienced something like this in broad daylight and at a mall nonetheless.

How likely is a woman to hook up with someone she just met at mall? To be clear I have no way of knowing whether those two had met each other for the first time or if they knew each other beforehand.

How does one normally achieve something like this?
