So then I would say the act of him sitting down at your table might be an act of 'social terrorism' more so than his expectation that you buy him a beer after accidentally spilling it.
There's no damage being done by him sitting at your table...but you don't want him there. The (subjectively unfair) social norm says that you should not ask him to leave unless he does something impolite/rude/damaging/etc.
(Hell, a large portion of the act of sarging is based on this norm...)
However, you didn't want him there...you wanted to spend time with your LTR.
So, it is very well within your right to ask him to leave you and your LTR alone (pre beer spillage). That may not be what many weak-willed people would do (they would just put up with his presence)...but there is no reason why you should feel any stress or resistance to politely asking him to leave.
Now, had you asked him to leave BEFORE accidentally spilling his beer, you would be well within all fairness to refuse to buy him a beer. At that point, it is his own mis-conduct that caused him to be where he was at the moment you accidentally knocked into him....and thus all bets are off of your wallet.

I think of it more as a cumulative process.
Social violation #1: Sitting at the table without being asked. If done correctly it does not have to be a violation.
Social violation #2: He sat at the table, didn't say a word, even after my LTR introduced herself to him. (She was working withing the politeness confines.)
Social violation #3: Being creepy while invading my private property.
Social violation #4: [b]Demanding[/b] I buy him a beer after I spilled it on accident.
Violation after violation. He continued to get his way until I stood up to him and said 'no.' In the presence of repeated, cumulative social violations at what point am I 'free' to engage in a violation as well?
He was simply holding us hostage. I don't think there's any other way to look at this. Then, when I spilled the beer, yes I was at fault, but in the presence of repeated violations and demands from a social terrorist I decided the appropriate thing to do was violate a norm.
Why should I be forced to comply with a protocol such as asking him to leave which then frees me to violate? When you violate, prepare for someone to violate right back. All too often, we allow others to violate us because society, wrongly, says that we cannot violate until we do everything possible to be nice and cordial.
