A stock boy is stacking fruit on a display, when a lady asks "Do you have any blueberries? " The stock boy replies "Sorry ma'am, we are out of blueberries, but we will be getting a shipment tomorrow morning" The lady looks around some more. A few mins later she runs back to him asking where the blueberries are. The stock boy confused about her mental state simply tells her "Sorry ma'am, we are out of blueberries, but we will be getting a shipment tomorrow morning" The lady looks around some more then goes back to the same stock boy and asks "Where the hell do you keep the blueberries, I need some blueberries right now!" The stock boy, getting frustated with his inability to explain the situation, tells the lady "Answers a couple of questions and I will get you your blueberries from the back." The lady agrees and the man starts the questions. "Spell cat for me, as in catastrophe " she says Ok, "C A T". "Very good!" the stock boy says, "now spell dog, as in dogmatic. " The lady getting frustrated spells it correct. Now the employee finally asks "now spell, Fuc, as in blueberries. " She replies "There is no Fuc in blueberries?" To which the stockboy replies "THAT'S WHAT I'VE BEEN TRYING TO TELL YOU THE WHOLE TIME!"
