6. Be Careful About What You Wear
If you regularly wear casual attire to work and then suddenly come into the office wearing a suit, it will arouse your boss’s suspicions. He will wonder if you are dressed up for a job interview. Find someplace to do a quick “Superman-style” clothing change. While there aren’t any phone booths around these days, the bathroom of a coffee shop will serve the purpose.
