Private public transport operators are yet again appealing to the Mia Amor Mottley-led administration to give them some relief from the high gas prices which are having a negative impact on their operations.Communications, Information and Marketing Officer of the Alliance Owners of Public Transport Mark A. Haynes told Barbados TODAY that the organisation is deeply concerned about the most recent hike in petroleum products which creates a headache for Public Service Vehicle (PSV) operators whose financial gains continue to be eroded as a consequence.Haynes contended that the situation is crippling and places operators under enormous stress in an effort to survive, as they grapple with other miscellaneous costs. He said the situation is not only unsustainable and untenable in the current economic climate, but it cannot continue unabated.
