I consider the question of free coffee to be a litmus test for any company. If you’re not offering it, you are unequivocally a loser not worthy of running a company:

1. It costs next to nothing
2. Caffeine makes the workers more productive
3. Your best outcome is workers who drink a healthy amount of coffee every day

The expected return of offering free unlimited coffee for any work place is positive - and the inverse of not offering free coffee is hence negative.
