Live is filled with many assholes and morons(at least the local ones near my apartment). Sorry for my language but during middle of this year, I had confrontations and verbal fights over idiots who think they know everything and criticize my play. Online, if you don't like someone writing all sorts of noise in the chatbox, you just mute them and move on. In live, you gotta take your chips and leave if you can't stand being with them.
Live is easier too. Btw. My highest stake when I go to casinos
is $5/$10 and even there, there are morons who call all-in bet of 300 blinds with Ace 5 as well as donkeys who do not know how to fold top pair(when I recall a bad beat from an idiot who sucked out with a running flush against my set)
I'm going to Vegas this winter. I hope there are less morons and assholes compared to southern California
If you're a winning player online, you'll definitely not have any problem with live. I'm a break-even player online who solely profits from rakeback/bonuses/freerolls. If you don't live in Southern California, you don't have to worry about jerks.
