Here are things that you should not do when in a coffeeshop or the cafe section of a bookstore:

Talk loudly on your cell phone in an extended conversation about how you're not qualified for a job because managers need to know how to re-key locks.

Tap your empty cup on the table in a rhythm matching a song only you can hear...in your own head.

Flip through magazines with your best friend and complain loudly how everything in there "sucks" "is so stupid" and "completely ugly."

Let your cell phone ring multiple times on different calls at the highest volume possible even though it's sitting right there next to you on the table.

Stand there, debating your coffee selection endlessly, while the line piles up behind you.

Sit next to me and do any of the above things when there are any number of empty tables near far less irritable people. : )

As you can probably tell, I spend a decent amount of time in the Barnes and Noble cafe. Even with the minor irritations, it does afford some awesome people-watching. Once I sat there and listened to a teenage boy on cell call swear up and down to his mother that he was filling out a job application at said Barnes and Noble for summer work, while he was actually thumbing through FHM and Maxim and the like. Too funny.
