What is this thing?
It's a public service announcement. You've most likely been linked here because you were thinking about asking out or hooking up with your barista (or someone else who you regularly interact with; see the page you were linked to). You should, uh... not do that.
Because they don't want you to. I guarantee it. Your barista is being paid to be nice to you - they're not flirting. They are, in fact, just waiting for you to shut up and go away so they can serve the person waiting very patiently behind you.
But this is different!
No it's not. Don't do it.
No. Literally just no.
I'm going to do it anyway!
Don't blame me when someone calls you a dick and you get a hard rejection.
