Change machine

So, on 1-27 the change machine took my 5 dollar bill and gave me one dollar back. So today I start asking where my change is from the pressroom manager. He takes me to the front office lady and asks her. She claims I musta done something wrong, but then, "oh I remember, I gave it to the bindery manager and it's in his desk draw, I didn't know who it was" she said.
So, I've been here a year this month, and this lady doesn't know who I am? And BTW, I give this same lady inventory every month. I guess I don't leave much of any impression on people.
