OK, I have one. Taxistas in BsAs get a bad rap, but one saved my ass after Aerolineas had left me, shall I say, "displaced." After my first-ever trip to BA, my flight home was scheduled for 10am Sat. morning. A couple of weeks before the flight, Expedia notified me that my flight had been moved up to 9am... what they neglected to mention was that it had been moved up to 9am THE FOLLOWING DAY. So 5am Sat. morning, running on exactly zero hours' sleep, I check out of my apt, leave my keys, and hail a cab to Ezeiza only to find out that I am 24 hours early. So there I am, in a near-empty airport, laden with 4 suitcases, all my valuables, no one to call and nowhere to go. I finally take a cab back into Capital, directing the taxista to the only hostel I knew of. No rooms available, but they suggest another one. Once again, no rooms. The cabbie, being very patient with my then-shaky Spanish, asks if I am looking for a room, and offers to take me to a cheap-but-clean hotel he knows of (probably his favorite telo, but whatevs.) He speaks to the desk clerk for me, arranges to pick me up the next day for Ezeiza, gives me a generous descuento, and before he leaves, draws me a little map of Congreso so I can find my way around. I always remember that story whenever anyone bitches about how all BsAs taxistas are evil.
