Using things for a purpose other than for the intended purpose for which they were sold
For example. A supermarket sells growing herb plants in the fresh vegetables section. Intended purpose is pull off the leaves and use them in cooking. Actual use, houseplant, no leaves ever removed.
A double example. An online business advertises printing a custom greetings card from an uploaded photograph file and sending it to a recipient. A supermarket sells photograph frames. Actual use, print of a card from an uploaded file of artwork produced on a home computer, sent to the customer, framed by the customer.
Car dilemma. Hoping someone can help!
