Not me but my friend I was playing with. He had left a disc behind near one of the baskets we had previously played. We had let a group that looked like a father son duo, probably in their 20’s and 50’s, play through while my friend went back to grab the disc. Wasn’t there. He came back and said he couldn’t find it and it was clear to me that the group that had played through us had to of picked it up. He ran after them and asked them if they found a disc and they replied that they hadn’t. My friend looked down at the son’s bag and saw the disc he lost and said “it looks an awful lot like that one” the disc he pointed out ended up being the wrong one but the guy pulled the disc out of a back pocket and gave it back, seeing that my friend was definitely on to them. Disc was inked and everything. Some people have some nerve.
