+1.....find a better mechanic. I'd bet you that chain will drop on the stand as well if the mechanic had tested/simulated the inner shift properly.
Better set that low limit screw properly and soon, like right now.
OK, don't tell me, he's a real sweet guy who is really nice to you when you go into the shop so you take him twinkies once a week. All that is fine but it doesn't do squat as far as preventing expensive damage to your wheel, derailleur and frame.
