If I work as a contractor through a management company and turn down projects, they're going to start paying someone else who actually wants to do the work.
And if I don't have the proper tools for the jobs, I don't get the jobs.
A 2 door car is not sufficient because the passenger is trapped until the driver lets them out.
A beat up junker isn't sufficient because passengers expect a car that will make it to the destination.
There's a very huge difference between not being available during certain hours and selectively saying "nope" to passengers.
