Summer brings out some really disgusting smells:-
– sloppy dog poo on the footpath
– rubbish bins sitting in the sun close to pick-up day.
– full rubbish trucks idling at pedestrian crossings
– the drain of the nursing home near my office
– people in confined spaces (think peak hour afternoon trains).
I've also noticed a frightening increase in the number of people who have really bad breath riding the trains!
