Greenline (or green line) bus service is quite a respectable inter-city bus service in Bangladesh. Many prefers this service for Dhaka to Chittagong / Dhaka to Cox's Bazar (coxsbazar) / Dhaka to Sylhet transportation. Usually they are good but they change their face before hartal (nationwide shutdown imposed by political parties). I was returning Dhaka from Cox's Bazar at the end of February, 2013. The bus was almost full and some foreigners were also travelling with us. We started on Wednesday night and was supposed to reach Dhaka on Thursday early morning. However, due to huge traffic on the highway we were a little late to reach Dhaka suburb. At this time greenline authority shows their angry red face to the passengers.
