Like the others, Quark is swept up in the good cheer of the moment and is oblivious to what just happened. He raises his voice to get everyone’s attention.
“Ladies and gentlemen, please do me the honor of accompanying me to my humble establishment. I’m throwing a party for the happy couple!”
A chorus of approval from the others. Dax shoots Quark a questioning look.
“What can I say? I’m a hopeless romantic.”
see, Dax knows that Quark’s loveaddled good cheer will wear off after the first couple slug juices, and he’s gonna be crying into her shoulder all night about how the love of his life chose someone else.
