More than 15 complaints a week have been lodged against taxi drivers in the past five months, including one case which resulted in a driver being fined for kicking a disabled man out of his cab.
Figures provided by the Department of Transport reveal 83 of the 352 complaints from passengers lodged since July 1 involve refusal of service.
Twenty-one of those complaints resulted in drivers being fined $200, including one who kicked a wheelchair-bound Mt Nasura man out of a taxi.
Tracey Moore's 20-year-old son, who did not want to be identified, was travelling with a friend from North Perth to his home about 3am on November 30 when the taxi driver pulled over in Maylands and kicked the pair out.
Ms Moore's son, who suffered a brain injury in a hit-and-run incident several years ago, then called another cab which took him home.
Ms Moore complained to the Department of Transport and the driver was fined $200.
"I was quite angry about it," Ms Moore said yesterday. "He should be sacked.
"It's against the law to kick someone out who is in a wheelchair. Who is to say he hasn't done it before and won't do it again."
Refusal of service was the most common complaint in the past five months, followed by issues with driver behaviour, driver standards and overcharging.
Of the 886 complaints made about drivers in the 2012-13 financial year, 244 involved fare refusal and 29 of those drivers were fined.
Drivers are permitted to refuse service to those who are too drunk or aggressive, who are unable to pay or who are likely to soil the taxi, and Taxi Council of WA chief executive Olwyn Williams said drivers often had to deal with these types of passengers.
"A journey for an intoxicated person in a taxi or a bus or a train or a plane requires decent behaviour and payment," Ms Williams said.
The debate over taxi industry standards was reignited at the weekend when media personality Lisa Fernandez said she had been kicked out of a taxi because the driver was unwilling to travel 10km to her Bayswater home.
Since posting about the incident on Twitter she has been inundated with similar stories.
A Department of Transport spokeswoman said the taxi industry encouraged passengers who experienced unacceptable service to lodge a complaint.
