A taxi driver
Take away my first letter and I am a store. Take away the second and people who look at me adore. Put all my letters back and read me in reverse if you are able. I am now cars suspended from an overhead cable. Take a letter away and I become male sheep. Did you get it, or did the letters you try to keep?
I know what my job is, The point has been made. You say I have a big head, And you're right, I'm afraid. Put me in my place, And then leave me alone. What I need most, Is someone to drive me home. What am I?
