As a Christian and a former Boy Scout, I don't help people as often as I should. You're late for a meeting or whatever, it's easy to come up with an excuse not to stop. Or just think "well, they've got it." Coming home from walking The Dog and there's a guy on the side of the road, trying to change a tire literally in front of my house. It looks like he's got things and knows what he's doing, but it's on the driver's side, it's rush hour, and cars are driving past him dangerously close.
When I get up there, I realize he does NOT have things under control. He's got a jack and a jack handle, but he's got a wheeled hydraulic jack and the handle for one of those mechanical "scissors" jacks. So he's failing to get the jack to pump. Since I've got a rolling jack in the shed, I go get it and head out to see if I can help. We got it done, but not without hiccups. Apparently he'd gotten the flat off and got the fresh tire on but the jack slipped or something, so first we used my jack handle on his jack. But because the road is on a grade for drainage and I don't think he had his jack positioned precisely, the jack tipped over once it started lifting. Luckily I was able to find a decent jack point for my jack (his was tipped but still wedged between the car frame and the road surface) and we were able to get him jacked up and get the tire changed. Even with all the right parts to the equipment though, I think a little emergency jack would've been a better choice, because even my jack rolled a few inches as it was lifting the car. Since we didn't have an cones or flares, I stood uproad from him and scowled at the oncoming traffic in hopes that no one would hit us (and to give warning if someone looked like they were going to).
Interesting, though. The guy apparently didn't know he didn't have the right jack handle. He was like "where can I get one of those?" And I said I thought you had to buy a jack to get one so he was going to see if he could find one at a junkyard when it occurred to me that he could probably also just buy a 1' metal pipe of the right diameter at a hardware store. I mean, one end wouldn't have the dimple that lets you use it to open the valve, but you can do that with a pliers anyway.
