Yes, I thought that was weird, Gersemi. If my parents had bought me £££ of stuff in preparation to go to uni and an item of it was then returned, there's no way I would have thought I had any claim on that money, how bizarre!
I tried kefir once, when it was going free at the homeless shelter I volunteer in. None of the homeless people would take it. I quickly understood why after I tasted it. As I struggled to finish the pot I thought to myself 'bloody hell, Tom Archer, you want to get back to your pigs. No one's going to buy this twice.'
