Boycott Addison Lee

Good for picking up passengers fast, but very bad for the drivers who might get two jobs in a shift. So the drivers are forced to lie that they have already dropped off their last passenger so they can get another job and make some money. So they are late to pick you up, and nobody's happy.

This is incorrect, as AL use reasonably sophisticated auto-allocate software. It is possible to cheat the system, but not in the way that you describe, as the software relies on GPS location to allocate work, ie you might clear the job before you're actually clear, but you still won't be close enough to the next job to be allocated to it.
