I stopped at the local Burger King for a cold drink and was reading the menu over the counter. I noticed a sign to the side that stated "Picture Menu Available".

I had to ask the clerk what it was for and they told me that they had a number of customers who couldn't read and they used that.

Of course I asked how they would know this picture menu was available and the answer was the classic, "Well, it says so on the sign, doesn't it?"
