Well, obviously I like my patients to be clean and smell fragrant. But. To be honest I care less what you look like, and more about why you have called an ambulance, and what your attitude towards me is. Unless I've had a really bad day, I'm always polite to people, and (accepting that illness/injury can affect how people react), as long as they are reasonable towards me then I don't really mind what people smell like. But I'll take a panic attack over a fitter anyday - much less to go wrong with a panic attack...
