The surprising thing here isn't that the yellow badges can't use the cafeteria, it's that OP's group could. The rule "the cafeteria is only for Apple employees" would be pretty natural and easy to enforce. If you want to make it so everybody has the same benefits, the easy way to do that would be to remove cafeteria privileges from OP's company. As for "and this person can witness this daily", if OP weren't muckracking, the yellow badges wouldn't know that his group was getting extra benefits they weren't. Anyway, how do they "witness this daily"? It's a big campus and you'd have to go out of your way to go to the cafeteria if you had no access or business there. Consider that I don't have a company car. I'm sure I could "witness it daily" that other people are being driven to work in their company cars if I knew where to look for it. But since I don't know about it, I feel fine.
