I hate wrapping tape. I'm a mechanical guy - not an aesthetics guy. I am up front about that with customers though. I will wrap and get it done if need be, and the vast majority of customers see no problem. I don't play games with people that are particular about it. If you're particular then wrap your own bars. I say as much, in a nice way, when I am checking in the work.
Not to say that I can't do it meticulously exactly the specific way a particular rider likes it - just that I have better ways to use my time if I don't need to fill that need. Like I could be meticulously preparing a pour-over coffee.
