Usually, no.
Here's the 'but...'
When I was using a LAer (before I became one myself), I felt she charged way, way, way too little. These machines are expensive, you don't just get one and be good without lots of practice, expenses, thread, etc. I usually added more because she did much more than a basic quilting for a basic quilting price. She also quilted my donation quilts as a co-donor for local raffles. Now that I've been doing this for a while, I can tell you that she was still seriously underpaid, even when I added extra.
I can tell you from other boards that the tips are celebrated because they are few and far between. I, for one, am thrilled when people grab a bunch of my cards because they want to tell their friends. Referrals are GOLD!! Tears and hugs also make my day. If you enter the quilt in a show, make sure to give her credit for the quilting, and if two ribbons aren't awarded (some shows give one for the piecer and one for the quilter), a picture of you with the quilt and ribbon for her wall is great, too.
