What do people have against egg yolks?

In an effort to get more protein in my diet, I’ve started eating an egg every morning for breakfast (in addition to my toast and green tea). My preferred egg preparation is over easy. I ordered it from the chef at our cafeteria. His response: “You don’t want the yolk broken?” Me: “No.” Him: “Don’t break the yolk?!” Me: “Um, no” (semi-self consciously at this point).
This entire week, every person in the egg line has ordered egg white omelettes, sandwiches, and scrambles. Not a single yolk to be found, let alone an unbroken one. What gives? I understand they’re fatty, but they also have the most nutrients. And to be honest, that runny yolk is my favorite part of the whole egg.
