Ok, guys I propose we find a way to settle this.
First I’ll ask the op: Did you go back to the store with the willful intention that you were going to deceive the guy into thinking it was covered under warranty? If so, I will grant that you are out. You were wrong, you stink and all that, no matter what happened.
I have been operating under the assumption that you did not intend this, but rather intended to get a second opinion and, like most of us, did not want to prejudice it by divulging the result of the first opinion. I think this is perfectly acceptable and prudent to boot.
