...no, it's not always true. I've grown to hate that saying, actually.
I had a horrible CP experience, mostly due to my trainer. It started off with frequent racist and sexist comments. I told him that this bothered me, and he told me I needed to have thicker skin. Oh, then there was the time he got in huge trouble for closing the ride capsule while I was still inside (I've forgotten the exact right terminology for it), and thank god Mission: Space has motion detectors in that room because otherwise the ride would of launched and I would of been killed. He was angry about getting in trouble and proceeded to basically make my experience there hell. And yes, I spoke to our supervisor about this. I tried several times, and each time they said they would handle it. Each time, nothing happened, and when I went back to talk to them again they did not even remember who I was or talking to me in the first place.
I love Disney, and I'm a very hard worker. I didn't go there expecting all fun and games. But when you have someone you see almost every day working their hardest to make your life difficult? And no one is willing to help? And everyone who actually cares about you and would normally give you a hug and listen to you vent is 1200 miles away?
...what good could I of made out of that situation?
Sorry, I'm not meaning this to sound like I'm bashing what you said. Just hoping for people to remember that just because someone has a bad experience does not mean it was their fault. That seems to be what's implied with the whole 'its what you make of it'.
