The wedding (Barney & Robin... Or is it he Bride's father who is supposed to pay for everything? Everyone is loaded (Especially Lily) so they're all going to be fighting to see who gets to pay for this shindig.) is paying for the drinks. I'm assuming it's an unlimited package, rather than itemizing for 200 guests, or a package for 200 guests.
But yes in review, that is definitely a Ben Franklin she passed over to Linus. Sorry.
