This happened today, I had finished work and was reading a text while I walked to the doors to leave work, walked towards the entry doors and stood there for a second, looked up from my cellphone when the door wasnt opening, relised it wasn't the exit, blushed a horrid red colour when I realised a workmate was standing watching me. Quickly kept me head down and half walk/ran to the exit.lol Oooo the shame. Stupid distracting cellphone... dont walk and read lol.
