Today I went to a Walgreen's drug store to buy some razor blades. When I walked up to the counter, the guy working there looked at me with a shocked and horrified expression for a second, then he recovered and said, "oh man, you scared me, I thought for a minute that you were a new employee." I didn't understand what he was talking about at first. Then I realized that I happened to be wearing a blue shirt that was the exact same color as the employee uniforms. He thought at first I was some new employee he hadn't met yet.
