It's not okay to be hypocritical about things in life.
Frank, who is an anti-smoking advocate is talking with Paul when Paul tells him their anti-smoking charity missed their funding goal.
Frank wants to ease his stress from the bad news.
Frank sighs loudly then reaches for a flask of vodka in his bag and takes a big swig.
Frank sighs loudly then asks one of the people around for a cigarette before lighting it and taking a long drag.
Paul sees Frank is drinking and asks him if he can have some too as it seems like a good idea to him right then.
Paul is disgusted that Frank is smoking when he's an anti smoking advocate and thinks Frank has no moral strength.
