Good, but be clear in what you want.

Friendly and helpful staff, willing to explain the mechanics and workings of things. Take care to be clear with what is needed and be sure to speak to the correct person. Recently had work carried out without a formal written approval on the quote, had a bit of a back-and-forth discussion, got a discount and all seems fine now. Be sure to deal with one person, it appears I brought the s****** in on a funny day and there was some broken telephone going on.
