Analysis

"This is getting embarrassing. I'm standing, marooned, being utterly ignored by the person I want to table-hop with."
What's happening at this time is that Becky is standing alone and Luke isn't responding to her greeting. It is really getting embarrassing to her because she is trying to fit in with everyone and "table-hop."
From this I can infer that Becky will embarrass herself even more trying to fit in with everyone else. It's already gotten her in trouble with money.
