imagine you get a cart from NGF, you asked for a new cart, with no extra stickers, stamps, etc, and to your dismay, they actually stamp your cart insert, and the cart itself is not in great condition. You ask for a refund, and Dion or Chris, in usual fashion, calls you stupid and stops responding to emails.
Now you want to sell the cart. What are you going to do. You paid $200 for it, maybe more. Are you going to be honest and say it was freaked, or pretend ignorance and describe the freaked cart as good condition (omitting the cart's history with NGF).
The buyer is put in a moral dilemma - be honest take it up the ass (like you deserve for dealing with NGF), or turn around and ass fuck an unsuspecting member of the neo community with that freaked cart.
Moreover, I could shit on my collection of carts - and that's fine. I could wipe my ass on every one of them and you can't stop me (of course I wouldn't do such a thing, but for sake of example). Yet when I try to sell the cart I better be damn accurate about what ahappened to the cart, because you'd kill me if I sold you a cart that smelled like shit. Now, replace the image of shit with stickers and stamps, and you have NGF.
However, in a year I suspect they'll actually start wiping their asses with leftover Zupapa carts and spreading them through the neo community.
