BC's Ministry of Transportation is monitoring complaints about Greyhound Canada in the wake of more customers being left stranded.
 
Government staff say they've been assured the private bus operators are investigating why one of their drivers walked away from up to 50 passengers at a gas station in Revelstoke earlier this week.
 
No explanation has been given, but the company's response will be monitored to determine if further action is required by the ministry which has the power to discipline Greyhound under the Passenger Transportation Act.
 
Tuesday's incident is one of several prompting complaints since mid-December when service has been disrupted by bad weather, bus shortages and drivers working long hours.
