I bring breakfast for my female coworker every morning.

She takes one bite, then gives it to the male designer.
After discovering this, I still bring breakfast for the female coworker every time.
One day, the female coworker didn't come in.
So I directly gave it to the male designer.
Later, the male designer started bringing me breakfast every day.
Each time I just received it in my hands, the female coworker would snatch it away from me.
One time, I got smart.
I took one bite first.
But then the female coworker threw the entire breakfast into the trash.
