I’ve just come across this story ‘Scent of a woman gets up bus drivers’ noses’
which tells of two different bus drivers in Canada who refused to carry a
woman because they didn’t like her perfume!

Can’t say I’ve had a problem with perfume smells on my bus, it’s more often
neglected body hygiene or carry on hot food which causes a stink. Megabus
forbid the taking onboard of hot food but sometimes it gets past the driver
because it’s in a bag and doesn’t give off its full aroma until it’s opened,
usually after the bus has started the journey and it’s difficult for the driver to
pull up and do something about it. Why is it bus passengers seem to favour
anything which has been lovingly deep fried in Duckhams 20/50?

Smell is one of the reasons why Megabus drivers try and stop the front two
seats directly behind them being used by putting their bag, jacket etc on this
seat. There’s little worse than driving whilst breathing exhalled garlic breath
from the passenger right behind you. The other reasons we don’t like people
literally breathing down our necks is that we hate being hit by sneeze spray
or, to have someone talking loudly into a mobile phone for hours only inches
from our ear when driving. One of the few benefits of driving the double decker
Olympians was that you actually had a cab in which to sit and be away from
the passengers. The ‘new’ coaches give you no space or privacy.
