1. most have hot bodies and the good ones have a pretty grill to.
2. they work nights so you dont have to take them out as often or give them as much quality time.
3. when they call you when they get out of work , they are usually a little tipsy and craving cawk.
4. you get to view the merchandise ahead of time. no suprises in the bedroom when they take off their clothes. suprises = cottage cheese legs/butt
negatives
1. they were humping some dudes leg all night
2. they will probably smell like cigarrettes when they get home.
if you can get past those..it can work.
