Dudley Magistrates' Court heard that Zafar Ali left Nicholas Mills "distressed and disorientated" after ordering him and his dog Percy to get out of the taxi nearly two miles from his home.
Mr Mills, 59, who is registered blind and relies on his guide dog to get around, said he had been quoted £6 for his taxi fare home. But he told the court that Ali said after picking him up it would now be £8 due to there being a dog in the car as well.
The court heard that Ali was working as a driver for A2B Falcon Elite when he received a call on August 8, 2019, to pick up Mr Mills from the King Arthur pub in Hagley. When Mr Mills disputed the increase in fare – Ali ordered him and the dog to get out of the taxi near to Stourbridge Golf Club, an area they were unfamiliar with.
A golf club member responded to Mr Mills' calls for help and found him in a "distressed and disorientated" state – before driving him home, around two miles away.
Ali, 68, of Vicarage Road, Lye, had denied failing to carry out a booking accepted by his operator, with the reason for that failure being that the disabled person was accompanied by an assistance dog. The offence is contrary to section 170 of the Disability Act.
But he was found guilty in his absence at Dudley Magistrates Court on Friday, October 8.
Ali was fined £1,000 and ordered to pay court costs of £595. He must also pay £200 compensation to Mr Mills and a £100 victim surcharge – with the total of £1,895 to paid within 28 days.
The matter will now be referred to the Taxi Licensing Committee, which will consider whether Ali is a fit and proper person to continue working as a private hire driver.
Councillor Karen Shakespeare, Dudley Council's cabinet member responsible for taxi licensing, said: "This is a totally unacceptable incident.
"Ali treated a vulnerable blind man with no dignity or respect and effectively dumped him on the side of the road, in the dark, with no idea where he was or how he was to get home.
"Luckily the kindness of a passer-by who made sure Mr Mills got home safely ensured that there was not a more serious end to this story.
"There was a very real risk of the man and his dog – in the distressed and disorientated state they were in – getting seriously hurt."
She added: "The fact it was all over £2 makes it even worse – it has ended up costing Ali nearly a thousand times that and rightly so.
"A committee will now decide whether the offence is serious enough to revoke his licence, with a decision made at a later date."
