Was onions all you had to deal with? The worst, and only bus trip I will ever take was on a road from Madrid to Sevilla for a festival, the trains were all sold out and plane tickets were to expensive.
The trip went through a lot of country roads and stopped at super small villages, the townspeople only had the bus sometimes to get from one village to the next. On one of these village stops this older farmer got on the bus and sat down next to me, phew.
Smelt like manure. I talked to him for a little while since I was trying to be polite and he ended up telling me that he kept goats and chickens which he had just finished cleaning up their pens and was heading to his sisters to help her and her husband with theirs.
Had to lather myself in lotion just to get the smell out of my nose.
