I was a waiter in and out for a year. It's tiring and you can end up exhausted.
But the needed skills were very simple.
Maybe it depends on the type of waiter? I served on the bar and only drinks, which was fairly easy. And of course I didn't own the place or anything. We also didn't serve any special cocktails or weird drinks. I didn't think that a special skill was needed to do what I did.
My ps1 controler have not gotten stick drift in.. how long now? 30 years?
Is that a lost technology like in sci-fi books?
