What's plan B ?

A friend of mine has recently decided to open up a new store in Kloof St and decided to call it "plan b", as it was never his original intention to open a store. He needed a logo and asked me to get it done.

I looked at plan b as a concept and realized that there is almost always a great level of uncertainty surrounding it. For example, in most cases when a character in movie states that "its time for plan b" its almost always followed by a question, "what is plan b?", "there is a plan b?" etc. So i used an upside down question mark as the b, to try bring across the uncertainty.
