Paddy was thinking of buying a coffee maker but was concerned it might be too complicated to operate. The salesman assured him it was easy to use.
"You simply put in the coffee and filter, fill the reservoir with water, slide the switch to auto and go to bed. When you wake up you can enjoy a steaming hot cup of coffee"
A few weeks later Paddy ran into his friend O'Riley.
"Paddy me boy, how are you enjoying your new coffee maker?"
"I had to take the stupid thing back" said Paddy, "every time I fancied a cup of coffee I had to go to bed"
