$50k/year per 150 people is 1$/day per person. How is that expensive?

$50k/year looks like a lot, but imagine you lose an equivalent of just one person out of 150 for not having it - e.g. in people leaving and not being immediately replaced, training costs, time costs of going into a corner coffee-shop to get some joe and returning 1.5 hours later, costs of not being able to hire top people because they like to be provided coffee, etc., etc. You'll see very quickly how it is not a wasted money at all.

150 people is a lot. Their payroll and benefits probably cost $10 - $15 million per year.

The moment coffee goes I go. So you could say it's more expensive not to pay for it.
