Have you got it in another colour?

Much discussion on the telly as to what your rights are when you wish to go back to the shop and exchange presents you have received. Am I alone in thinking that anyone who is even considering such a course of action should be put in the stocks and pelted with rotten fruit?  These are PRESENTS for heaven's sake - you haven't paid for them, and even if they turn out to be not what you wanted or expected, you should accept them with good grace.  What ever happened to the idea that "it's the thought that counts"?
