Dad had owned a very successful Gulf and tire business with a partner for 25 years. He was a smidgen too young to legally sign the contract when he opened it, his dad signed for him. The original partner sold his half to a young whipper-snapper, local boy fresh back in town from Brazil (petroleum engineer or some such). Had NO mind for business. Dad dealt with it for as long as he could stand the situation, then sold his half to the "new" guy ... who quickly-enough ran the whole thing into the ground.
Good Gulf, No-Nox, Gulf Wax, yada yada.
