No, its a silly tradition, what does he own his daughter or something? it has nothing to do with him.
I would ignore my future father in law if he said no, but I would do it out of courtesy as I know that's what my girlfriend wants me to do, and what he expects. I don't generally like meeting their expectations, but this is a big deal.
Probably best just to ask in case?
Tradition suggests it might be best to. It also starts you off on the right foot, even if he says no.

I know it will be fine, but I just think its bloody awkward.
Her family is very different to mine. An example being she has probably had about 20 meals at my parents and I have had 1 buffet dinner at Christmas at hers.
I think if we knew each other better it would be less weird, I think she expects me to do this but I don't see the point and don't want to be made to feel like an idiot trundling over there.
I'd do it, assuming we got on, or if the wife to be thought it was a big deal. If he's a knob, and she doesn't care, he can swivel.
It'd probably be weird if you had no relationship with them beforehand - probably a good excuse to try and get on with them a bit relatively early on!
Last paragraph exactly. They are more than nice, just different. I know they like me but I feel really embarrassed doing it. I guess from the feedback I should just suck it up and do it.
How did you guys go about doing it?
