Crewdroog: Tipping: in restaurants, servers don't make minimum wage. They might make $3USD/hour. I don't know what asshat thought it was a good idea, but they don't. Instead, they make most of their income through tips left at the end of the meal. I have traveled to Mexico and England and tried to leave tips not thinking, and given very odd looks. 15% of bill is average tip, 20% is for excellent service, 10% is a F- you. No tip? Don't go back, they will remember you and do things to your food ;)
We are loud and friendly (for the most part), but are very serious about
personal space. We don't like people being too close, and strangers touching you, unless it's a handshake, is weird. If there is a park bench or bus seats that are empty and you sit close to someone, they will appear agitated.
Flags!! They are everywhere! And not just US flags: state flags, sports flags, war flags (POW: MIA, etc), peace flags, rights flags (gay, etc), ethnic flags (polish, irish, italian). Flags saying places are open, having sales; it just goes on and on.
