Which is exactly why I don't do this.
It's retarded.
Yes, I know Bob the Fighter's usually more than average selfish, won't open a door until after Tommy the Lock (the only person he really trusts) checks it, and doesn't have the personal initiative to build the freakin' fire without being repeatedly asked, but suddenly, today, he's volunteering for all sorts of tasks, spending money like water, and pushing Tommy out of the way at each door.
Yeah, that makes sense - I'd be asking for some Sense Motive checks for mental domination, myself.
I prefer to live in the real world, where real life things - extra required work hours, sick kids, etc. - occasionally intrude. And, frankly, I'd have to be a much bigger bastard than I am to say to someone, "Hey, Bob, I'm sorry Suzanne got sick and you had to spend all last Saturday in the ER. Welcome back, though - oh, and your character gave away all his magic items and then died mysteriously. Feel free to make a new one, though."
