Horrible experience with alterations - long rant

I went into a custom sewing and alterations shop yesterday. I've had the appointment for months and was so excited to see what they would do with my dress. The woman was very cold and short with me on the phone when I made the appointment but I told myself that she was swamped with prom season. My mom and I walked into the salon and were taken back to the area where I could change. She came out, started pinning, asked if I liked it, and told me to take it off before we talked price. All very quick and short. I took it off, saw the price (almost triple another quote I got earlier in the day) and she told me to sign at the bottom of the quote. I asked her if I needed to decide if I would have her do it today because I was feeling uncomfortable with her attitude and the price. She said "well, yeah, you really need to decide now." So I told her I'd call by Friday if I wanted to go with her. I went back into the dressing room to collect my things and my mom said she ripped up the ticket, threw it in the trash, and stomped off into the backroom. I am DEFINITELY NOT going with her! Just had to rant. This woman is a professional and has a beautiful salon,but charges high prices and has the worst customer service I've ever experienced. Did anyone else have a bad experience??
