I had a bad dream. I woke up and found that my home was full of free stuff. Free food for my dog. Even a free entertainment center. Not too shabby for a bad dream.
Trouble is, nothing is free.
Not even in a dream. My free fridge was given to me on the condition that I purchase all my food from a supermarket owned by the fridge manufacturer. In fact, my groceries are automatically delivered to me based on the current contents of the fridge. The items in the grocery order are selected according to my prior eating preferences, with allowances made for holidays and birthdays, which I input through the appliance keyboard. And of course, if I want an extra bag of chocolate chip cookies, I can add them into the order manually.
