I am a longarmer and I do not expect a tip and have been thrilled maybe 3 times when someone paid me extra, usually when they needed change from cash and told me to keep it, lol. I would never expect a tip from someone even if they did tip previously. I really don't make an expected income from what I do, I just provide a service for quilters who would never have a finished quilt unless I quilted it for them. (I do not have a "business" so to speak, just regular friends that I quilt for.)
