I worked with a lathe operator that bought a truck and started pumping septic tanks, then he started buying and renting out job johnnie's, bought a yacht and retired to Florida at 35. When he quit work maybe 10 years later, he owned over 600 portable toilets. Reminded you of Pig-pen from peanuts, crusty all the time. How we laughed when he pulled into the parking lot for 2nd shift and he had his first 4 toilets.
