Public speakerphone use has become so pervasive that SEPTA, Philadelphia's transit agency, has resorted to posting signs on buses and trains pleading with passengers to stop. The agency's humorous but pointed message - "Unless the tea is REALLY hot, keep the call off speaker" - signals that this behavior has crossed from mere pet peeve to widespread nuisance.

Speakerphone use in public spaces has become increasingly common, with passengers apparently unaware that holding a phone to their ear requires less effort than holding it out in front of them. The phenomenon extends beyond transit to grocery stores and other public spaces, where conversations about everything from family gossip to medical diagnoses become public performances. Even when people lack headphones, the logic of playing music or videos without consideration for others remains baffling.

The transit agency's intervention suggests this isn't just about individual annoyance but a collective frustration that's reached a tipping point. While some public tech annoyances have clear explanations - like needing to unwind after work - the speakerphone epidemic appears to stem from either obliviousness or a complete disregard for shared public space etiquette.
