I consider this a rather pathetic excuse to get out of helping someone. Red to red, black to black. Mark cables with polarity (engraved will do) and just put them on the right battery terminals. Really, it's not THAT hard, people! And I don't believe someone can't spare 2 minutes to help a fellow Human who's stranded.
Just because it you don't find it hard, doesn't mean that others don't. And it takes more than 2 minutes, because I've helped give jumps and I've had to give them. And the whole process still kind of scares me. So without trying to sound snarky(truly), yes, it can be THAT hard. And the "fellow Human" usually isn't "stranded". They are usually (and in the mentioned case) at home or in a populated center. I very much doubt that anyone on these boards would leave someone truly stranded in a remote area if they could any way help it.
Any boss who gives you grief for being a little late, should be fixed with a "look" and the comment "So, helping my neighbour with a jump-start so they could get to work is . . . bad, is it?"
And that would be a rude response.
Fliss, I understand that you seem to be passionate about this, but I believe that people should be allowed to say "No, sorry..." and not be lumped in a group of "horrible people who don't care about other humans". And that if someone would choose to help and be late to work, that they would be just as nice to their boss who expects and pays for them to be on time. An "I'm sorry I'm late, here's why I did it, I understand that I need to take responsibility for my decision" and then accepting the repercussions, is not only polite but much more likely to make everyone feel better.
