I've got a waiting area in my garage. If customers have to wait they can do so. I damn sure ain't advertising it though they are generally 5 to 10 feet away from me. I just tell them to stay seated for the entire performance. 

I personally never thought I'd use a plotter, but I went to one 3 years ago and I'll say : if you do dealer work on a lot of the same vehicle, you would be amazed at how many more cars you can tint in a day!  So far I've used 3 different pattern companies ( due to changing jobs, starting my own buisiness etc.) all have good/bad patterns, but I always have had good service with getting bad patterns fixed. Especially if it's something I see a lot of

LMAO, pretty good is a relative thing! I've been tinting for 20 years, and I'm sure there are plenty of things that these guys could show me and vice versa. If tinting is something you want to do to make  a living doing, then get a job at a high volume shop and learn everything you can. You'll know when you have, because the other guys will be coming to you for help. (PS it will take a few years) But please strive for something better than pretty good!
