My radiator hose blew while I was sitting in heavy traffic on Hunter Mill, a block from Chain Bridge Rd. I managed to get off the road quickly. I noticed that my overflow bottle was also disconnected. It appears my previous service center repairs were faulty. A Good Samaritan stopped, reconnected both, and refilled my antifreeze. He recommended I have it checked by a mechanic, just to be sure. I visited the closest service station, but all of the mechanics had left for the day (4:57pm). I was told to go to James Madison Shell. Luckily, they had a mechanic who works after 5pm. Andre checked my hoses, topped off the antifreeze, allowed my car to run for a while, and rechecked everything for leaks. I was there at least 20 minutes, and was charged nothing! Knowing little to nothing about cars, he could have told me anything, and charged me whatever. Thank you Andre for being honest, and helping out a driver in distress, all for nothing in return. I found 2 Good Samaritan's that day!
