I'm fine with doing activities by myself, if no one else is interested. The paying-someone-to-pretend-to-like-me idea is just sad. If you want friends with the same interests as you, join a scrapbooking/sewing/sports/whatever group. You can actually meet people for free, who will be your actual friends...although I know this sounds too good to be true since it's free.
Probably not a full refund, I would think it's the same rules that apply to trading in a used car. You would be better off donating them to a needy charity
Shit, I don't care about renting a friend, how does one go about getting paid to hang out with people? I have no life, it's perfect.
I did not have any immediate plans to do so but after consideration I should probably keep it in mind.
