A man walks into a cake shop

A man walks into a cake shop and asks for a cake in the shape of the letter e. The clerk says no problem come back tomorrow. The next day the man goes back and is presented with the cake. “No no this is all wrong. I need a lower case e, this cake is an uppercase E. Please can you make a new one, I really need it today?” The lady reluctantly agrees. The man comes back in the afternoon and is presented with a cake in the shape of lowercase e. “Perfect, just what I needed. You’re a life saver!” The lady asks if he would like it gift wrapped. “No thanks, I’ll just eat it here.”
