It was just that Subway! I manage a Subway in Ellensburg, Wa. and We bend over backwards to make everyone happy. Bad news travels faster then good news and we know that. Our Subway is #4 out of 122 Subways in our region, and our goal is to be #1 by this summer. I hope you went on line and filled out a complaint on them, that will help with maybe getting rid of that employee.
good luck and please don't give up on Subway.
