I agree -- most people are good and mean well. Unfortunately, not everyone see's their "good deed" as good. A few years ago when we were at Epcot we were sitting and enjoying some snacks in the outdoor seating area in France. While we were sitting there, we noticed a Disney Parks merchandise bag on the ground along the wall about 10' away from us. We watched it while we finished up our snacks and no one ever went near the bag. Thinking someone may have left it behind, we walked over to it and gently tried to look inside thinking maybe it was just a bag of trash. It wasn't. There were some pricey souvenirs in it. We asked other people in the area if it belonged to them. No one claimed it. One person said it was there when he sat down and he was there before us. We looked around for anyone who might have been looking for it (thinking they might not have remembered exactly where they were sitting when they left it behind). So after a total of about 5-7 minutes (starting with when we first noticed the bag), we decided to take it in to the gift shop and give it to a CM. No sooner did we walk out of the gift shop when we heard a young woman (probably in her late 20's) having a meltdown screaming, "Someone stole our bag!!!! Who would just pick up a bag that wasn't theirs and walk away with it???? What is wrong with people? I can't believe someone stole our stuff!!!!" So of course we waked over and told her that after watching the bag for over 5 minutes, we gave it to a CM so no one would steal it. She continued to flip out -- yelling at us for touching her stuff, saying we stole her stuff, etc. Someone else who knew what we had done yelled at the lady and said she should be thanking us for turning it in rather than walking off with it. The woman continued to rant saying she and her husband had "just walked around the corner to take a picture and had only been gone about 10 seconds." <eye roll> We just told her the name of the CM we left her stuff with and walked away. I'm sure when she got home she told a story about how some crazy people took her bag of souvenirs when she was standing right next to it.
So apparently even the "good guys" are bad sometimes.
