My mum, 78 year old, uses public transport extensively.
The other day she wanted to get to a particular plant nursery and walked down to her nearby bus-stop. A bus was there already and she asked the driver if he went past the nursery.
"Yes" he replied. He then looked at his watch and said "Look, I don't start my next run for 20 min. Hop in, I've got time, I'll take you there now."
And he did.
There are some wonderful people out there.
