I don't remember having to sign any contracts during the purchase.
Signing is not necessary. It is implied in the purchase. There are signs clearly posted that dictate the terms.
WDW did not sign a contract saying there would be a variety of cold carbonated sodas available either. But I bet if all they had after you bought your mug was warm flat Mr. Pibb you would be the first to raise a complaint.
The thing is, it's not even the stealing that gets to me. You know what? I steal stuff too. I have in the past, and I am pretty sure I will again in the future. But I call it for what it is. If the caishier at the grocery store forgets to charge me for a item, and I walk out with it, I stole it. I have done that very thing and that makes me a theif. I have no qualms about admitting it. It's not somthing that I am proud of, or that I brag about.
What I do NOT do is make up some way to justify it in my mind. "It's a big store, they can afford it" "Everybody does it" "I am sure they overcharged me before" "I shop here so much I should get a break" All of those are just cop outs to make you feel better when you know that you have stole something.
Me, I don't re-use my resort mugs, but if I did I would be the first to admit it's stealing. I have yet to see somone on any message board have the courage and vindiction to be comfortable with their character and admit what they are doing. It's allways justified by some lame excuse.
I guess I am just an honest theif.
