Sales person took measurements to give a quote to replace existing rear entrance. Explained details and gave us an instant quote. Upon further discussion, the sales person made deductions to the quote including a portion of his commission. When we said that we were not signing a contract today, just getting quotes, he SLAMMED his laptop closed and angrily stated "well, I won't take up any more of your time". User's recommendation: BEWARE OF PRESSURE ALWAYS GET MORE THAN ONE QUOTE.
