I often take this green line sleeper bus from Chennai to Bangalore as it starts very close to my house. The bus drivers drive extreme rash.
Sudden brakes, small accidents even before leaving the city limits is usual. You’ll have a stinky bed sheet/blanket, extremely cold AC and mosquito filled most of the times.
Double berths are even more un-comfy. U’ll b rolling in every turn.
Once a passenger was drunk and was shouting on the phone in profane language. None bothered to make him quiet.
