My personal experience. Tried to run a catering business 15 years ago. Everything needs to be thoroughly controlled and cross-checked, employees start stealing the moment you turn around. It certainly started impacting my personality by the end of this sad experience, making me bit by bit a paranoid misanthrop.

Years later, i found out that my coder employees scammed me too, so i had to quit hourly tracking and only take on fixed price jobs, and ensure markup is able to absorb anything.
