This reminded me of this time I was in Gamestop, and a guy came back to return a game. Can't remember what the game was. Walks up to the counter with the manager at the register and says "I beat this game and didn't like it, so I want to return it." Manager refused the return since he told him he beat the game. Is that at the manager's discretion, and did he have the right to do that? Pretty dumb of the customer to mention he finished the game though.
Also, you have to play all the way through a game to see if you like it? LOL.
