well now going on 5 hour delay. bus broken down in Knoxville. greyhound does not seem to care about customers. Nothing offered as free lunch in area while waiting or some rebate for local place to eat. They don't even send a back up bus to knoxville, just say, well your 8:45AM bus might leave knoxville at 12:00 noon,maybe.It was bus breakdown. I believe they should be responsible. Airlines after such wait for plane failures, give rebates for airport restaurants.The rest rooms are also disgusting. greyhound sucks. AVOID AT ALL COST!!!!!!!!!!!
