It’s happened to all of us: You’re out to eat, enjoying some conversation, the restaurant’s carefully curated ambience, perhaps the muted tones of a couple arguing nearby. Some bearded man whisks by and drops a plate off at the table. The chefs have artfully arrayed the ingredients such that you’re not even sure what each of them are anymore. What mysterious flavors might this new dish hold? And then, before you can dig in, across the table, the phone comes out, because if you don’t post a picture of something you eat to Instagram beforehand, did you really even eat it?
