I found that to be a strange reason, as if being pleasant were the goal (hello, Willy Loman!), and the value of smart phones, and not doing something actually valuable with one’s time. In that sense, my smartphone can help make better use of my time in waiting rooms, but of course, that’s up to the user. You can choose to waste your time.

If you find something that makes you no longer mind waiting (and therefore more patient) or makes you not be so anxiety-ridden when you get your appointment (like a doctor's appointment)... Wouldn't you be more pleasant, and that pleasantry would come more naturally rather than forced, would it not?

Smoking can also make you mind waiting less, and help you cope with anxiety during an appointment (though I would really like to see a source on the negative correlation between phone use and anxiety, because I don't believe it exists). Does that mean that lighting up in the waiting room makes you more pleasant to be around?

I really just want to know though: is this something you have decided makes you more pleasant to be around, or have others told you it?
