I used to play with a guy who always made charisma his highest stat. Didn't matter if he was playing a fighter, had to have the charisma. He just wanted to get all the characters around him to suck up to him without providing anything of value or even a logical reason, RP-wise.
I got him to make a sorcerer, once, but he killed off half the party with area of effect spells while trying to kill some random dudes... who were actually just messengers... and were also rogues with Improved Evasion. BUT I HAVE A HIGH CHARISMA SO EVERYBODY LIKES ME. ALSO IT TRANSLATES DIRECTLY TO INCHES.
Anyway, depending on the stats for really basic social scenarios seems like asking somebody with an 8 STR to make a roll to open his front door. All it says is "I'm punishing you for making a choice I don't like." Hopefully, a decent fighter will be able to get a decent reaction because he has a reputation from his heroic deeds... or fear from his evil deeds... rather than turning everything into American Idol: The RPG.
