I've never returned a used item just because I didn't need it any more. I have returned defective items, but that's a different story.
I own a tour company, and we used to donate trips to various charity functions. The donation was always very specific, and in fact I started doing up a sign og my own for the trip - it was always for 2 seats on X tour at X date, had to be at least 18 (or 19, depending on the state). Not redeemable for cash, can't be used for other trips etc.
Every single time I had calls from the winners asking if they could book a different trip, or have the cash value for the trip. Every time these donations were made I knew the nature of the fundraiser - each time it was a silent auction and these people had bid specifically on that item. It just seems to be that if you're bidding on an trip, for a specific date and with specific requirements, that you ought to know that's the trip you're going to get if you win.
The casino/resort we usually deal with just opened up a whole new hotel wing. Their marketing people sent out invitations to a couple of hundred VIPs (ie big gamblers) inviting them to stay at the hotel for a few nights, free. I spoke with the reservations manager shortly after the mailout went out, and she was amazed (and horrified) at the number of people who were calling to say they couldn't take advantage of the free offer, but could the casino send them the value of the hotel room in cash instead? I told her she needed to tell people "We really value your business, and we'd love to have you come up and see our new expansion. We're really sorry that you're not able to make it, but unfortunately I'm not authorized to pay you to stay home".
On our trips we have (at our expense) a hospitality room. No other tour company has one, we pay for it because we wanted to provide one for our people. We supply snacks and soft drinks, there's a microwave and coffee maker and we supply popcorn and coffee. We also bake (a lot) and bring cookies and so forth for the room. We also provide magazines, playing cards, a crib board etc. The only thing we ask is that people actually use/consume the items IN the room, as the purpose of the room is to encourage socialization. We've had large amounts of food disappear within hours of being put out, last trip one of the passengers took the crib board, although she did leave a note saying that she had it, despite having a note in their itinerary saying not to remove stuff, a note on the door stating the same, and my saying it at least 3 times during the many hour bus ride there. One trip I had left my lunch in the fridge there, with my name on it, and someone ate it. I was going to say that I couldn't believe what some people do, but the fact is that yes, I can. And I'm not surprised at much anymore.
I even walked into the hospitality room once to find one of the women having a conversation with her friend - the problem was that one of them was in the bathroom (actively using it) and had the door open and the other one was standing nearby. These are co-ed trips, it could have been any of the men who walked into that room, they're lucky it was me. Or maybe they weren't, because they're not allowed back on my trips any more (I also had other complaints about them).
I'm SO glad I don't work in retail, or have to put up with other people's policies. I'm happy making my own. It's bad enough when people cancel the day before the trip (because "something came up) and then expect a full refund.
