Was on the train/tube last week when a man in his 30s got ont eh train rucksack and straggly dog.
He proceeded to get out his camping tin bowl, open a can of dog food stick it in the bowl and put it on the floor for the dog to eat - which it did. No problem at this point.
There was food left, so he then proceeded to pick up the bowl, get out a spoon and finish the dog food off and lick the bowl clean before putting it away.
The woman sitting next to him, was dry heaving and the rest of us were not far off having a small chunder.
What travel behaviours have you witnessed that make you stomach churn.
