Although teachers, dentists and shop owners in my opionion are not PERFORMANCE BASED ENDEVOURS FROM A COMPETITIVE STANDPOINT. I DO CHECK MY CHILDS TUTOR TO MAKE SURE SHE IS CREDENTIALED, I RESEARCH MY DENTIST TO SEE IF HE HAS ANY MALPRACTICE SUITES PENDING AND I DON'T KNOW ABOUT YOU BUT, WHENEVER I BUY A BUSINESS, I DO ASK TO LOOK AT THE BOOKS!
