So last summer we started looking around for vendors and going to bridal expo's and just happened to stumble upon a pianist and really liked the idea of having one play some old jazz songs for cocktail hour and dinner. Im a music person, have been in band and jazz all thru middle school and high school band and decided to splurge for it because again i thought it'd be really cool. Well we got his brochure and it said $300 for cocktail hour and dinner, kind of steep but YOLO. (yes i just said yolo) So we set up the appointment and got to talking to him, and put down a deposit, not realizing that it was just for a plain jane electric keyboard it would be an additional $300 for a baby grand piano. Well fast forward a year and i just can't justify spending that much for a couple of hours. Now my question is how or what should i tell him that i will no longer be needing his services and need my money back without sounding rude?
