Smelly people
When people dump their rubbish on seats
People who take two seats
People with loud music
People who talk loudly
People who DON'T PREPARE THEIR MONEY BEFORE GETTING ONTO THE BUS, and therefore spend 2 minutes searching their bag
People who stop the bus when the bus has previously stopped at a bus stop that was in walking distance to that bus stop...if that makes sense
I remember once I came from the airport from abroad, I needed to get home, I had a large rucksack, a large hand held bag and a suitcase. At the time there were no seats on the bus, but when a woman got off an inconsiderate woman who obviously could see how exhausted I looked from carrying all my bags, took that seat when she had nothing to carry.
Another time, the was a guy behind me, who had the most smelliest breath ever, which me to smelling my hand for the rest of the bus journey, literally sneezed onto the back of my head...I used Detol to wash my hair that night...
