Came here with a girlfriend to get some work done since it's too hard to in your own home sometimes. From experience and years of going to coffee shops to get work done, common courtesy is peacefulness. This doesn't mean you have to be completely quiet but it means don't scream and laugh loudly when it is clear and obvious people are here to do work. Instead, we found crazy mocha houses groups of weirdos who play games like dungeons and dragons and make ridiculous noises and scream very loudly. The best part was when we started talking they looked at us like we were being disrespectful and interrupting their \""nerd time\"". If this was  Starbucks they would've politely asked them to quiet down then leave. I work with the loud public all day long and a coffee shop is my escape which I couldn't get here tonight.
