Most of my work at the moment is touring. I just love doing it, I mostly tour Ireland, and some parts of the UK, Belfast, Edinburgh, Glasgow, etc.
Certain places do have a certain rhythm in terms of how the traffic flows. Also where you stay in the town, or city you are in can also affect business. When I am touring in Dublin, I use to stay in the city center, but then so does everyone else, now I stay at the Airport, and business is fantastic there, less competition, plus there is a large suburban area around. And the hotels at the airport are great for this, loads of traffic, so no one notices comings and goings.
And to answer your question, yes it is part of the job, having wankers call and book fake appointments. What I find helps, is asking them to reconfirm the appointment about a half hour before. If they don't call, I have no problem giving that spot to some one else.
Look to see what events or holidays are happening in the area you choose to work. Also, if it is summer time, head to holiday resort towns! Trust me, a week of camping with the wife and kids will drive most men to drink or screw.
