My mechanic family member told me to never offer to boost anyone because if I'm not comfortable doing it, if they screw up the terminals, it will fry my battery. Which is why I have auto club for myself too.
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.
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?"
As for an 'Auto Club', I'm happy you're able to afford it. We can't. So, the few times I've needed a boost, I've been dependant on others helping me -- just as I help those who need it. Generosity of spirit is part of being Human.
Sorry to disappoint you, but not everyone is a shade tree mechanic. i am not comfortable jump starting a car, even going by the pictures in the manual. I don't do it often enough to remember is it live black to dead black, dead red to live red? And I'm not a roadside assistance service, so I don't feel obligated to engrave my jumper cables so I can remember how to handle someone else's inconvenience.
And I'm thrilled beyond belief that you've had bosses who would respond positively to a 'look' and a 'Really, boss?' Just about every place I've worked that would have earned me a serious black mark, if not a write up for insubordination (on top of the lateness). Just as it's not really my problem to spend 10-15 minutes (not 2) jumpstarting a stranger's car, the consequences of my Good Samaritan impulses are not my emplpoyer's problem either.
I'm sorry you can't affort auto service or alternate transportation if your car breaks. But these things happen, and if your car is that unreliable it would be your responsibility to have alternate plans made, not my responsibility to bail you out on demand.
