Sitting at a restaurant reading while I eat is a normal thing for me. People know me as that guy. They make assumptions like that I only read paper or Kindle then ask when I show up using the other.
Last week a guy sat next to me and kept me from reading due to his need to talk. He was bragging about being a slow reader. That he only reads dense academic history with more endnotes than text. And switched to talking about the Olympic skating needing a 100m event. He never read while I was there and interrupted me when I tried to return to reading.
All the while I was thinking the reason he cannot as much as he wants is he is easily distracted.
