Amazing coincidence - I was on the bus today when a youth got a big python out of a bag on to his lap - woman across the aisle then protested to the driver who told him to put it back - after claiming it was "only a little one", which it certainly wasn't, he did bag it up again.
I think the poor woman was quite distressed (understandable, snakephobia being quite common). I think if I'd been the driver I would have thrown him off the bus - a most unreasonable way to behave IMO.
