Consider that all these lunches are subsidised by the company, which if you think about it could have either completely subsidize or pay workers more and make lunches full price. This lunch format easily costs 8€ or more full price.
Side note: I actually do like for companies to subsidize lunch since it's usually money that is exempt of taxes up to a point (depending on the region) so the workers save money by doing so.
Euthanasia is a personal choice. It's completely different from whatever the fuck you are implying.
