Imposition is number 1. You don't talk to people. People assume you don't want to be talked to. Sometimes dive bars are just for seeking oblivion. Picking fights would be #2. Getting mad when losing - you've chosen to interact in a friendly way, but getting pissed off when you're wrong, that's just not fair. You lose the fight, you own up to it. Also, dive bars over serve, almost as a rule, in spite of the post. Getting drunk and hitting on women or men to excess, I dunno. hard to explain. If you're polite, you can get absurdly drunk. Don't inflict your drunken-ness on others. --edit-- I realize after a moment #1 is confusing, especially for non Americans. it's always ok to introduce yourself. if you get a grunt in response, it's a lack of interest. in the south, you might get a warm welcome, because that's just hospitable. There's a bit of reading involved. If people try to engage you in conversation, asking you questions is a good example, you're welcome to participate. A dive is generally older men drinking away their pensions. But it's diverse, lots of ages, genders and income levels. You just sorta have to read the audience. Feel free to stick around for perhaps 5 minutes and listen, but if you're ignored, you're probably not welcome. An American would be loud and pushy and "be an asshole"
