Bristol bus atrocity

One of the girls in work (Leigh) was shocked today. She'd traveled in by bus as she always does. The bus was three stops from the Hospital and it stopped. The bus driver (who had been a grumpy git the whole trip) got out of his cab and came to the back of the bus, he stopped behind her and addressed the girl sat directly behind Leigh.
Leigh said she turned round slightly and identified another nurse from the Hospital in a staff nurse uniform. The girl was from a Black ethnic group.
The bus driver started to shout at the girl. He said she hadn't paid enough, that she'd paid up to zone A but this was now Zone B.
The girl replied that she'd paid £ 2.80 as she always did and she had no more money on her.
The bus driver said he wanted her off his bus now.
Leigh turned around and asked how short of fare she was. She was told 90p and Leigh got a pound out of her pocket and tried to give it to the bus driver.
He pushed it away and told her this wasn't her problem and to mind her own business.
Then he frog marched the staff nurse off the bus and drove off.
Leigh said she almost got off with her, but was panicked at being late for work (she has to open the unit up)
As the bus passed the now walking staff nurse the bus driver said quite loudly "Fucking black Bitch"
I begged Leigh to report him, she took his number. I hope she does. Absolutely disgraceful plus I know of no single fares (it was before 8am) within Bristol that cost £ 3.70.
