I delivered for Domino's while in college. Bought a $1000 POS dodge D50 mini-truck and considered it 100% written off as 'cost of doing business'. Sipped gas and ran like a top.
I made somewhere approaching $10/hour consistently in the mid 1980's. In addition, I made friends with the Mgr. and Asst. Mgr, both of whom wound up becoming franchisees. It was tempting, at that time (early '80's)...
But I did it for a year and a half, kept gas in the truck, lots of free pizzas to take home, and a little $ to keep life & limb together.
Sold the Dodge D50 for $1200 one week before graduating. LOL
Kinda nice, DEFINITELY a short-term fix for most, but it could mean having the cashflow you need.
