It's a Texas Thang
Having lived in Texas, I assure you this is true:

Go right ahead and patronize the guy in jeans and a lamentable workshirt, and look down your nose at that beater of a pickup, if you must, but be warned, you do so at your peril. Around here, he may turn out to be the third richest man in the state, the chair of Classical literature at a major university, a leading heart surgeon, or the President of the USA. Or he could just be a small rancher from the Panhandle, but damned if you'll be able to tell by looking, and if you get suckered into a poker game, don't tell me you haven't been warned.

I miss Texas.
