Yeah, I used to work a job where I was basically on call for 6 hours at a time, but didn’t need to do much unless something broke. I’d help set things up at the top of the day then tear things down at the end. But in between, I was basically just waiting for things to break. It’s safe to say that I used the fuck out of my gaming laptop and VPN at my desk. Because I obviously didn’t want to try playing games on a company computer.
I played a lot of single player and idle games at that job, because those are easy to walk away from at a moment’s notice. Just hit pause and you can give your full attention to whatever problem has popped up. Then once it’s resolved, you’re right back where you left off.
