AITA for refusing to carpool with my coworker?

A convenient carpool arrangement between two coworkers living just blocks apart quickly became a daily ordeal for one of them. The driver enjoyed cutting commute time in half by using the HOV lane, while the passenger avoided slow public transit. The setup seemed perfect—until the passenger’s intense, onion-like body odor filled the car and lingered long after each ride.

After two weeks of enduring the smell, the driver honestly explained that the odor was too unpleasant to continue. The passenger became upset, arguing it unfairly doubled his commute and transit costs. The driver’s girlfriend suggested he should have first asked the coworker to shower or use deodorant. Now the driver feels guilty, wondering if ending the carpool without softer suggestions makes him the asshole, or if the ongoing issue justified his decision.

‘AITA for refusing to carpool with my coworker?’

It seemed like the ideal setup when the two coworkers discovered they lived just blocks apart.

The daily drives soon became intolerable due to an intense odor.

Honesty led to confrontation and second-guessing.

The main issue is that the driver suffered real, ongoing distress—40 minutes daily in a confined space filled with a powerful, lingering odor that made his car unpleasant to use even after the coworker left. Since multiple people at work had already raised the hygiene concern without any improvement, the driver reasonably concluded that further suggestions would be ignored. Ending the carpool was a valid boundary to protect his mental well-being, daily mood, and the condition of his personal property.

On the other side, critics—including the driver’s girlfriend—believe a direct but kinder conversation suggesting solutions (better hygiene products, medical check-up, etc.) could have shown more empathy. Sudden termination felt harsh to the coworker, who lost a significant time and money benefit overnight. Some medical or environmental factors (like diet, medical conditions, or living situation) might explain persistent odor despite basic cleanliness efforts.

Broadly, this reflects how informal favors can quietly shift into expectations. Being upfront, even if uncomfortable, often serves as the clearest signal for change. Prioritizing one’s own health and space in shared but non-obligatory arrangements is generally seen as fair, especially when prior warnings went unheeded.

Here’s the feedback from the Reddit community:

Many users strongly support the poster’s decision, highlighting that he owed no lifelong ride and that honesty may ultimately help the coworker address a serious issue.

A smaller group offers more balanced or empathetic takes, recognizing possible medical or situational causes while still supporting the poster’s right to stop.

A couple of lighter, humorous comments ease the mood by pointing out the universal awkwardness of the situation.

This story illustrates how a helpful gesture can quickly become unsustainable when one person’s personal habits severely impact another’s comfort and property. The driver chose direct honesty after previous complaints went nowhere, while the coworker felt blindsided by the loss of a convenient perk.

What do you think—was ending the carpool the right call, or should he have tried one more suggestion first? Have you ever had to address an awkward hygiene issue with a coworker, friend, or roommate? How did you handle it? Drop your thoughts and experiences in the comments!
