10. Striking up a conversation with the person next in line

The Starbucks crowd is not a particularly friendly group of people. To tell you the truth, at any given time, majority of the Starbucks population are caffeine-crazed zombies who are out on an errand to get their dose.

11. Not knowing how to use the WiFi

Okay, so using the WiFi at Starbucks is not as easy as connecting to your WiFi at home. It needs a tiny wee bit of effort and an extremely little amount of tinkering on your phone. No, you don’t need to cut the line to the counter and have the barista give you a blow-by-blow. Just remember to click “Accept & Connect”.
