At Intel, they have this system where you're either a blue badge or a green badge. Blue badge, you're an engineer, you're a top admin. If you're a green badge, you're a subcontractor. Which means you're at the bottom. I was a green badge.
There's special events, like the end of the summer, outside with a carnival, If you were a green badge, you were not allowed to go to the picnic, not allowed outside. Since we made the food, we got to eat it anyways - as lunch. But we weren't allowed to go outside and play the games. You could only look. You couldn't touch.
They had it very separetd - by class - as I liked to say, segregated.
Honestly, making those weird little coffee - that was a chance to do something different. Other than that, you were invisible. You were an invisible worker. Things got restocked magically.
