In my opinion, short and unhelpful. I went into this Window supply business with a question and a picture. I was just seeking some expert advice. I’m sure we’ve all looked for some guidance at some point.The person behind the counter seemed to have no interest in helping or understanding my problem. He kept rattling off, is it a true window, is it a storm window. I thought I was clear when I first started. It’s a double hung window that tilts in for cleaning. Nothing unusual.Oh well, my friend. It’s ok, Mr. Google was a gentleman. It was simply the balance shoe that needed to be engaged.Peace.
