As far as standard wainscoting height being a % of the wall height, by that guideline that would mean that homes with 8', 9' and 10' ceilings would all get significantly different wainscoting height: for the 40% example, 8'=38, 9'=43 and 10'=48. I don't see that happening...
Chipotle founder Steve Ells. McDonald's took on Chipotle as a subsidiary in 1998 and largely financed the chain's rapid expansion. But Chipotle founder Steve Ells has less-than-kind things to say about his former parent company, which spun off the burrito maker in 2006 to focus on its core burgers and fries.
McDonald's was a major contributor to Chipotle's success. The burger chain made an investment in Chipotle in 1998 that helped it grow from 14 locations to nearly 500 within seven years. By 2005, McDonald's had a 90% stake in Chipotle's business. But one year later, McDonald's divested its stake and parted ways with the fledgling burrito chain.
