I tend to play limit games at casinos
, so I seldom run into major jerks. Tempers seldom flare too much at limit tables. The fights, the screaming matches, break out at the NL tables. If someone is yelling at someone else, it's at a NL table. If someone is saying "But it was soooooted" it's probably at a NL table. People win and lose more $$ at NL, and get more upset.
You did nothing wrong. He was a dope for calling with such an awful hand. Plainly has no understanding of the gap principle. Your button raise preflop was not awful, but his call was. His turn suckout was killed by your river suckout -- so be it. He was also obnoxious by keeping his cards face down, although I don't know if it is necessary protocol to flip them in a ring game showdown. That's more of a tournament thing, I think. If the dealer says to flip them, then I do it. As i say, I do not play NL ring.
Saying "sorry" is a bit of a beginner thing. Most players stop saying it after awhile. It made it clear that you were not very experienced, and, no doubt, they then thought they could push you around. I don't say "sorry" much -- I find that it seems to be rubbing salt into a wound most of the time. And, well, most of the time, I'm not sorry. I'm especially not sorry if the other guy had garbage. I may sympathize if the other person had a great hand preflop (like AA or KK) and played it well but lost to my suckout. Been there and know the pain. Thinking about it, I have to say I am still not sorry, but I do empathize.
After that, he and his friend were trying to rile you, to get you to play their game, try to get you off balance. Good for you for sticking to your guns and playing your own game. Sounds like it worked out well for you, too. Which is the best revenge, isn't it?
Remember that, if you dislike the game at one table, if you are finding that other players are tilting you, you can ask to be moved to another table. Most casinos have more than one table at a particular limit. It's not a big deal. That said, a table with some active LAGs, even if they are jerks, can be awfully profitable if not fun and friendly.
The most important thing is to maintain your own balance. Wear an ipod and pop in the earpods if necessary.
