The worst that can happen because you decide to ask someone something? You go up to say something to them, stutter a few times, throw up in your mouth a little, and then they say "No".They laugh at you, and all the people around turn around and it turns out they were listening and are friends, and also laugh at you.
You turn and look into the cafe window, the barista is staring at you and shakes their head patronisingly.
You feel a sudden panic attack coming on - maybe you've never had one before - it feels like your chest is in a vice, you can't breathe, you piss yourself and collapse on the floor. Someone calls 911.
An ambulance turns up, by which point you feel OK again. You have to explain to the paramedics that you had a panic attack because you asked someone to get coffee. Their faces.
Someone took their phone out and had been recording the events. Cloudy face recognition picks up who you are and tags your name onto the clip.
You are making your way home when the police call you; somewhere along the way the events have gone down in the paperwork as a fraudulent 911 call. Nobody can tell you how.
Your insurance company hears about it and your insurance is provided by your employer. You are laid off from work.
