How do I quickly log out of GTA Online after a competition ends? (Grand Theft Auto 5)

After the end of the race (for example) I see what it says came out from some. Where to click to immediately exit the game after the case is over?
I don't know, so every time I switch to free mode, I wait for it to load and only exit from there.
I mean the lobby where they vote for the next case. It says B to exit but this is also an exit to free mode. I play on the joystick xbox360
