We have the nicest plumber you can imagine. He wears booties and cleans up after better than it was before. He is extremely courteous and well spoken. He had an intern type last he was here, a young white guy, the plumber is black, bald, 6'5" tall, and has a great smile. I keep thinking up more jobs just to chat again.
The intern dude is also very polite and well spoken, he "sounds" like he could handle college just fine.
