Two years ago while I was checking us into PC, DH and DSs were browsing the gift shop. A man approached DH and gave him 6 CS meal vouchers, saying they were leaving and didn't use them...I think they were some kind of DVC promotion..We ate well off those vouchers, they included meal, dessert, and drink!
Last year at EE, the kiosks for FPs were backed up because the ride was temporarily closed. The CM's were handing out the FP's without putting the tickets into the machine. I went through the line a couple of times and got several tickets for us. The ride became operational, but we ended up not using all of them, so while we were on our way out, I handed 6 FP's to someone coming in. They were thrilled!!
On another previous trip, DH, myself, and DS7, DS9 were standing in line for POTC. It was about a 1/2 hour wait, and while there we struck up a conversation with a man who was there from Australia. He was alone on business in Orlando, and came over to WDW because he never got to go when he was young. In fact, he said his parents took his DB, but not him because he was only 10 (I almost started crying about this..) Anyway, DH was glad to have someone to talk to, admired his cameras. He gave DS7 a little clippie Koala Bear, and DS9 a clippie Kangaroo (little stuffed animal that has a spring loaded clip in it's arms so you can clip it on your collar or whatever) They both had t-shirts on that said "I (heart) Australia. I was so touched by his gesture. We saw him again later on in the day and waved and said, "hi".
