编辑同志:今年春节期间,我和妻子回老家探亲。我们从长途汽车站购买了车票并经检票上车。汽车出站行驶约两小时后,因机械故障不能继续运行。我们要求退票,但汽车售票员却以车站规定当汽车出故障不能运行时,只能为乘客拦截其他汽车运送而不能退票为由拒绝。请问,在这种情况下,我们有权要求退票吗?王成 Editor's Comrade: During the Spring Festival this year, my wife and I went back to visit their relatives. We bought the ticket from the bus station and got it on the ticket. About two hours after the car is out of the station, it can not continue its operation due to mechanical failure. We asked for a refund, but the car conductor at the station stipulated that when the car failed to operate, it would only be refused on the grounds that the passenger intercepted the other car and could not be refunded. Excuse me, in this case, we have the right to request a refund?
