The final sentence "We bet nobody’s gotten into a fight while waiting for that oyster party" contributes to what Editor Scott Hensley had said about going downtown and waiting in line with a "friend" rather than buy tickets online for the Old Ebbitt Grill's annual Oyster Riot. It had put up to saying that people waiting in line had too much fun to even "start a fight", like how people complain that they don't get refunds from returning tickets online, or when people give a bad review that, who knows, could start something big in the future. Waiting in line make's you interact more with the people or friends around you, having a bigger probability of having fun rather than starting one of those sibling fights. Of course, some people often don't like oyster or seafood, but you can find yourself waiting for oyster on a line tomorrow, lauging with your friend louder than the megaphone they use to call out names for oyster soup. Who knows.
This is from another question, tbh if you just search for your question you are likely to find a response.
The only change I know of was the silk road, where they had to build roads and clear forests so that traders could go through. I don't think any other geography changed during that era.
