Gift Exchanges

We had our bunco group Christmas party last night. It was lots of fun and the food was good but I do have one question. Why do people bring total crap to a gift exchange that you're supposed to spend $15 on? It's almost like people walk around wally world or someplace similar and pick up the first thing they can find that costs around that amount. I know that it's hard to find something that would suit everyone in the group but don't buy no-name brand bottles of irish creme, neon green bathroom towels or a $15 gift card to MickeyD's for a group of adults. It's just one of those uncomfortable moments when you're sitting in the circle and and someone opens the gift that you bought and you're wondering what everyone else is thinking. I would have rather gone home with mine than what I ended up with!
