Which character's statements might reflect a sentiment of frustration about communication?

The bartender's statements are likely to reflect a sentiment of frustration about communication due to the context and role they typically play in narratives. Bartenders often serve as informal confidants or observers of the interactions around them. Their comments might highlight misunderstandings or the challenges that patrons face in expressing themselves, especially in a setting where emotions are running high or where complex issues are being discussed.

Additionally, a bartender's unique position allows them to witness various conversations and relationships unfold, giving them insight into the struggles individuals might have with effectively communicating their thoughts or feelings. This can lead to a sense of frustration, particularly if they see repeated patterns of miscommunication or if they themselves are trying to maintain order in a noisy or chaotic environment. In contrast, the other characters might not embody this sentiment as strongly, possibly because their roles focus more on action, personal conflict, or other themes rather than the subtleties and frustrations of communication.
