Ink Spot Copy Shop

This place was easy, affordable and helpful.
The store owner went out of her way to make sure I was taken care of, and told me that if anyone of her employees was ever out of line, to let her know and she’d sort ‘em out.
Great neighborhood printshop for my daily printing needs!
Remember:
Cash Only

In from out of town, I called in ahead to have a print order priced, which was quoted at $ 17 for a half size set of architectural drawings. So I doubled the order to have two sets, and emailed a PDF file as requested.
Arriving at the shop to pick up my order, the total was $ 50. The man working and I figured out that the miscommunication occurred on the phone, where he misquoted me because he thought I needed «copies» and not «prints» despite the fact that I mentioned I would email a file (did he think he could make «copies» from a PDF?).
I then offered to A) pay the price he quoted on the phone B) pay for and take only one set. Instead of accepting either of these terms despite his own mistake of misquoting the price, or offering a different compromise, he decided to destroy the sets.
Needless to say, I’ll be taking my business elsewhere.
UPDATE: The owner actually emailed me the next day, apologizing for the mistake, and offered the sets to me at $ 1.75 per sheet, which I calculated to be the original cost which was quoted to me on the phone. Definitely, I support small business as much as humanly possible, but I had already found someone else to do the work (for cheaper, actually)(and for the record, NOT a corporate chain) and had the drawings in hand by the time I received this email.
Now here’s my thinking: after already having been turned away by one of his employees, and given the fact that he’s going to destroy the documents anyway, the owner needs to do more than offer for me to drive back to his store and sell the documents to me at FULL PRICE (which I already offered while standing in the store). I’ve already spent time, energy and gasoline only to be turned away, and I expect more, if nothing else than a sign of good faith and good business.
I really, really, really don’t like giving negative reviews, but I feel the need to hold this business accountable. I hope the best for this small business, and invite them to correct this wrong and affect my opinion.
