There was a wait for tables at the restaurant S and I went to on Saturday. Here's a look at how people passed the time. You may notice a similarity (sorry the pictures are a little dark):
Very few people were "just" talking—without their phone in their hand (and in one case, an iPad). Instead, people would view media (e.g., a video, a game) on a device and offer commentary. Or they were texting (and updating the group about the message). Or they were updating a Facebook status. Or taking a photo.
These scenes are definitely not anomalous. What are you seeing? Send your pictures of people waiting and using technology as a means to pass the time to comments[at]anthropologyinpractice.com and I'll share them here on AiP.
