Loose Red Grapefruit

A stockboy is stacking fruit on a display, when a lady asks "Do you have any grapefruits? " The stockboy replies "Sorry ma'am, we are out of grapefruits, 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 grapefruits are. The stockboy confused about her mental state simply tells her "Sorry ma'am, we are out of grapefruits, but we will be getting a shipment tomorrow morning" The lady looks around some more then goes back to the same stockboy and asks "Where the hell do you keep the grapefruits, I need some grapefruits right now!" The stockboy, getting frustated with his inability to explain the situation, tells the lady "Answer a couple of questions and I will get you your grapefruits 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 stockboy says, "now spell dog, as in dogmatic. " The lady getting frustrated spells it correct. Now the employee finally asks "now spell, Fuc, as in grapefruits. " She replies "There is no Fuc in grapefruits?" To which the stockboy replies "THAT'S WHAT I'VE BEEN TRYING TO TELL YOU THE WHOLE TIME!" (edited)

Thanks OP. Love grapefruit. Must have a look.
For those not aware, if you take meds, don't take them soon after eating grapefruit, as it has the effect of doubling the dose
