I do not believe the "dude who came in guns a blazin" was part of the customer base. In fact, I'm near certain he/she wasn't after seeing that he/she contacted certain people with information only someone outside the customer base would know.
I can't see how any regular customer could think AD was closed. There were signs at the Patton Creek location posted for weeks, as well as a sign posted on top of the counter with the new address prior to the move. But, at the same time I know how easily rumors are spread...
Just a word of warning from experience, be wary of Sean. Yes, for the most part he is a nice guy, but only when it is advantageous for him to be so. I'm not here to praise or down him as a person, RC isn't the place for that, just keep your eyes open.
