We became pretty familar with lost and found this May. The first incident, dh "lost" his prescription transition sunglasses (he had them in the case, in his pocket, he thought) - he had been wearing another pair of prescription sunglasses, as the transition ones weren't getting dark enough for him. He realise they were missing as we were going into the Lion King show at AK - and thought they had probably fallen out in the bathroom earlier - so he went back there, and we stayed for the show. A few minutes after he left, I found the glasses in the sack I was carrying - which he had handed to me as he left LOL I tried calling his cell phone, but he never answered - so while we watched the show, he was trailing around trying to find where lost things go
He was pretty happy to get his glasses back after the show, but his feet were hurting
The next thing he lost was a Mickey Mouse baseball cap - he left it in the pocket of the seat at Thunder Mountain - we didn't realise until later, so didn't bother going back (this time my feet were sore, so I promised to buy him a new hat so I wouldn't have to go on a hat hunt). The next day we happened to be passing through the TTC, so went to lost and found - and lo and behold, they had it !! Dh was VERY impressed
The last thing we lost was a sack of souvenirs - we were on the Buzz Lightyear ride - I rode with ds, and dh was behind us. He put the sack on the floor, and left it there. We realised when we had walked through the Noodle Station, and I went to the bathroom - and when I didn't have a plastic sack to hang on the back of the door, realised it was missing
Dh went back to the ride, asked in the gift shop, and then spoke to the CM at the end of the ride (I think). They had the bag, but he had to describe in detail what was in it - thankfully he remembered (among other things, it had the photo from ds's pirate league visit) - so we got the bag back. Phew !!
Needless to say, I got very good at doing hat and bag checks after that
