I've been to this location a couple of times with an OK experience, but tonight we arrived 3 minutes before closing and the clerk had already turned off the open sign and locked the door. We tried to walk up to see if he would change his mind but he wouldn't even look up for at least a minute, endlessly staring at the floor or at the walls in an attempt to avoid eye contact...low class move. I would have minded less had he simply acknowledged us and said "sorry we're closed". It was almost closing time - I understand wanting to go home - but regardless it's not the way to treat customers.
I have contacted what I presume is Smoothie King management (Greg) about this as well.
