It's a legitimate disability, and certainly I don't envy anyone with this issue. We've all been taught that people who have maybe acne or body odor or sweating issues or dandruff or whatever else are just people with "poor hygiene", but the reality is that products and buildings are made to meet the needs of the most 'average' person (usually defined by a company selling something), and there is so much variation in how bodies function. When you're trying to make a product that maximises usage and sales, it's ironically easy to exclude a lot of people.

Thanks for being kind to that person, I'm glad you were able to see (and smell) past it.

For anyone else who does experience limitations because of their body odor, check out the Job Accessibility Network's list of possible accomodations for this symptom of your disability. Because medical issues that cause you to be ostracised and limit your ability to function in society are a disability and you deserve an equal opportunity to thrive.
