I have always made a special point to meet AND THANK the mechanic who actually does the work. This goes for cars & bikes. This is especially important for me because I only have "it" done if I don't think I have the experience or proper tools to do it myself.
Everyone likes to know his/her efforts and expertise are appreciated and valued. Do this a few times and he/she will know whose bike (or car) it is and that it's owner will appreciate the a job well done.
In addition to being a good way to help ensure a job is done well, it's good old-fashioned common courtesy.
