What should he pay?

Ju

I just saw a video where a couple guys were arguing with their friends over a really high restaurant tab. The men were saying they should only have to pay for what they ate. Pointing out that bottles were purchased that they werent even drinking and several of the others got high priced dishes. The rest of the party was saying they should all split the tab evenly and birthday girl shouldn't have to pay. There was a big argument and the man filming said he lost a very long time friend over it. What do you guys think? Should they have split evenly or everyone pay for what they ate? Should birthday girl pay?
