Here is the reason, I chose the ruler strap for my extremely naughty, house maid Emily. I left her cash for Uber rides, specifically because her license was suspended, for making a silly decision, earlier in her stay. If she had a license, I would have gladly left the keys in her hand, rather than locked inside my drawer. She decided that she would take that chance by breaking into my drawer, taking my keys and driving on that suspended license. Why you ask, would she be willing to leave so much to chance? Nothing more than to pocket the extra cash! She could have been pulled over and had nobody to post bail. Not to mention possibly losing her license for a very extended amount of time. The bite of this strap, was just a piece of her punishment, when I discovered later, how sneaky she really was!
