Physical Place and rules/ social codes

Rules and social codes. Whether spoken or unspoken, they dominate our society. While observing my surroundings I noticed some interesting things. The social codes and rules of appropriate clothing, language and noise level change depending on the place. In general, it seems that the more expensive and public the place the stricter the rules and codes. I received some first hand experience in this when eating out and going about town with my family. A perfect example of this is when I went out to eat at Café Tavolini in Bridgeport, an upscale Italian restaurant. When I went there, there were no young children (12 and under) all of the men wore button down shirts and the women dress pants or skirts. One man was even asked to leave the restaurant because he was talking too loudly on his cell phone and disturbing the other patrons. This is compared to the Burger King I went into on my way to New York on the 26^th where all of the restaurant patrons were in various states of dress, from pajama pants to suits. Volume wasn’t an issue since the place was so crowded that you were expected to yell your food order to the staff in order to be heard. This just leads me to wonder if the rules and social codes are meant to attract a certain group of people or if the people a place attract unconsciously create the rules and social codes.
