“I saw a guy at Starbucks today. No phone, no tablet, no laptop. He just sat there drinking coffee”

Some people—very few these days—go into a coffeehouse like Starbucks and simply drink coffee. Brooklyn-based Wall Street Journal writer Jason Gay‏ made a popular tweet on September 22, 2015:
 
“There’s a guy in this coffee shop sitting at a table, not on his phone, not on a laptop, just drinking coffee, like a psychopath.”
   
The jocular line has been printed on many images.

In a September 2015 tweet, columnist for The Wall Street Journal Jason Gay brilliantly highlighted how normal a constant absorption in technology has become: ‘There’s a guy in this coffee shop sitting at a table, not on his phone, not on a laptop, just drinking coffee, like a psychopath.’
