It all depends on the company for sure. I'm not sure about the laws in EU, but in the US you genrally have with X amount of employees you must have a space for eating, break room, etc, and with X more employees the company must provide food service on site.

Some choose to subsidize some or all of the food. Basically the FS provider would submit a bill at the end of the other to the company to make up the difference. Boy, let me tell you, those meetings were super fun!

We had one company provide coffee to each floor (4, plus exec level), and said coffee was kept in unlocked cabinets in the coffee room. Our first bill to the company on coffee alone was 10k (for about 600 employees), and then it went up from there.

Flash forward to an average 20k in coffee a month and the meeting with the CFO to see what feasibility to take out the coffee machines and replace them with soda fountains... GOOD GOD CFOs are the most dense, single minded motherfuckers on the planet.

I'm no longer a part of US corp. life and I feel cleaner for it.
