Now, "someone who can not take care of himself" is probably a turn off no matter the type, but who gives a rat's ass if he's always late to work? Unless you are also his boss and looking forward to that pre-meeting fuck early in the morning.
I agree. I could care less that my partner is frequently late for work. It's not like I'm his mother/keeper. Perhaps if I depended on him being on time for some reason (a la carpool situation) then it'd matter a bit, but then if he couldn't shape up I'd just find another mode of transportation, not dump him.
