Recently, the practice of online ride-hailing services imposing air-conditioning fees via QR codes has ignited a wave of controversy. Some drivers are charging passengers an additional 3 yuan for air-conditioning, justifying it by claiming that 'discounted rides do not cover the cost of air-conditioning.' This issue has elicited varied reactions from netizens, with some contending that discounted rides should inherently entail cost savings, while others raise questions about why basic services like air-conditioning are subject to extra charges during scorching weather. The Jiangsu Consumer Protection Commission has emphasized that the fares paid by passengers should inherently cover the expenses of essential services, including air-conditioning, and that any unauthorized surcharges constitute a breach of contractual agreements and legal regulations.
