I'm not in SF, so maybe this is ignorance on my part, but how common is it for employers to provide lunch for their employees? Is that a Thing now? A few years ago, it was a big part of news stories about Google, how they have in-house chefs and lunch is free to all employees and all that, and that seemed like a big deal at the time. Has "lunch for employees" trickled down to small companies and startups? What % of startups do that? And is there a split between VC-backed startups and bootstrapping startups regarding who does/doesn't do it? ZeroCater seems like a good solution to that problem ... I just had no idea there were so many companies doing that. Would love to hear experiences of people here.
