What difference could you make in haircuts?

Not much you may say. I beg to differ. I was watching a TV show the
other night and I saw someone performing a haircut underwater and
charging upwards of $200 per haircut.

What got me interested was Onsite Haircuts, whose service is described as

Onsite Haircuts is devoted to a single idea: providing a quality
haircut with the least interruption to your busy life. Get in. Get out.
Get on with life.

If you are outside the bay area, the service may not be available at your location yet!
