Public transport in the morning. Worst thing ever. Granted probably 90% of people are "fresher" and cleaner in the morning than in the evening ... but it's also when they smell like they have doused themselves in perfume or cologne (I imagine them lining up and being herded through a sheep dip, the smell is so intense!). My poor sensitive nose can't handle it ... I sneeze a lot, and I feel like I am breathing tainted air.

I think it's probably mostly because they use spray perfumes or colognes. It's hard not to resemble, scent-wise, a cloud in those circumstances.

It makes me desperate to get of the bus, and also gives me a headache.
