AF hmm…well 'it's more than friendly banter' could be interpreted one of two ways. The way I interpreted it, is that it is flirty banter with a hopeful agenda, as opposed to non-flirty banter with no agenda. Whereas you obviously read 'more than friendly banter' as 'dangerous, predatory sex pest alert.' 
Women know when their boundaries have been crossed.
Er…yes they do, of course, but not everyone else does!
in the OP's case, she doesn't fancy this guy, fair enough, so her boundaries are somewhat different, I imagine, to what they might be if she did fancy him. We'd be hearing 'ooh, do you think he likes me? He put his arm around me the other day in a friendly sort of way so I'm not sure if he's flirting or not, but he did joke that he could fall in love with me for liking McDonalds - what do you think? Does it sound like he's interested? He did mention the cinema...' 
Yet, everyone says 'Oh he's just being friendly, he's just angling for a date.' So the woman is left feeling like a rude bitch while the man pushes and pushes. Conveniently if he rapes or assaults her, he can say that she never knocked him back. Lose all round for the woman.
So he's a potential rapist now? 
The way she talks about him anyone would think he spent all his time cornering her, groping her and whispering lewd comments in her ear, not hinting that he'd like to take her to the cinema. I know it's a bit icky if you really don't fancy someone but maybe he's just one of those socially inept guys who is not very good at judging social situations, body language etc. It's not a reason to be downright nasty to him at this stage, I'm sure he'll get the message soon enough if she just gives him a wide berth and is a little aloof.
Or, he's from a culture where the sexes don't mix freely and sees British women as fair game and a sure thing, in which case OP by all means, put him in his place as firmly as you like, because he is showing you huge disrespect by treating you differently to they way he would expect his own sisters to be treated by a man.
But based on what the OP has said, I really don't think it's fair to assume at this stage that he's a creepy potential sex attacker who needs to be barked at to keep his distance. At least try to let him down the normal way first. Then if he's a thick skinned creep, by all means up the ante.
