Freebase animal tranquilizers, inject grain alcohol into your temples, still none of your neighbors will bat an eye. They're all too busy drinking Robotussin DM and fortified wine to pay attention to you. Besides, they might think you're attempting to steal their luggage. You'd be surprised how protective Greyhounders are of their possessions. At any sudden movement they will clasp the duct-tape wrapped trash bags which contain all their worldly goods tightly to their chests, and stare balefully out at you with their beady eyes.
Thievery is a fact of life on the bus.
My friend at MIT took a bus from Boston to Detroit. During the ride someone stole an old man's dentures. One of the reasons for vacationing is to meet new people and have new experiences. Take my word for it, this is one experience you can live a happy life without. Not to be elitist, but a bus ride is like a trip to the Club Med of the dangerously indigent.
