Back in the day, Disney did have a "customer is always right" mentality. Over time it morphed into a customer is almost always right mentality--which is what it was when I was sent by my employer to the Disney University--a fantastic experience with a ton of takeaways to bring back to my team!
A few years later I ended up working for Disney as a Cast Member. Because Disney had been far too lenient for far too long, we were barraged with scammers who thought that they could pretty much get away with anything. That was no longer the case, and I saw pretty drastic changes (relatively speaking) in that time frame.
Back in the day, Disney pretty much had a policy to never confront a shoplifter, just let them go instead of creating a scene. Now they trespass them off property or even prosecute them.
One of my biggest "wins" ever was with a lady who I knew was shoplifting and putting things in the sleeves of her daughters snow jacket that she was carrying. I walked up to her with a shopping basket and quickly grabbed the coat out of her hand in a single movement in a way that everything fell to the floor while saying, "Let's put the coat into the basket to give you free hands to shop with." When everything fell out of the sleeves and to the floor I scooped all of the merchandise up into the shopping basket and acting very innocent, I told her I'd hold it all at the cash wrap for her and bring her another basket. And then I handed the coat to the little girl and told her, "Mommy has a lot of things she's trying to carry for you, why don't you carry your coat to help her out." I didn't need to take another basket back to her, they were out of the store in under four seconds.
For many years Disney took tickets at face value, now they have sophisticated systems to spot cheats and will confiscate tickets that don't conform to their purchase and use requirements. They even got the State of Florida to pass laws specific to the use of theme park tickets.
Disney has also gotten very savvy with people trying to scam based on faked injuries and such. No longer will a report of a scratch from a shrub hanging 1/2" over a fence gain a free hotel room night or a comped dinner at a fine restaurant. At best you might get a fast pass. And that's of you allow them to call the paramedics.
Instead of quietly investigating theft, assault, harassment, or other crimes by employees, they now inform and fully cooperate with law enforcement--even though they know their "dirty laundry" will be aired as a result.
They also have begun enforcing use of facilities by those who aren't supposed to be there--the wristband system at the Stormalong Bay pool complex comes to mind.
I had to smile at your final sentence, because I have to say "no" on a regular basis. I've learned to do it in a way that my customers often end the conversation by saying, "I guess that was a pretty ridiculous thing to ask for to begin with. I'm happy with what I've got. Thanks for your time and explaining it all to me." That's how I know I'm good at my job. 😁
