umm usually a little steeper than 10 bucks. usually upwards of 20. If the fellow is driving a older model car; older than 10 years old, chances are he or she may not have the coin. I know, I've been there. Seems like alot of people have the idea that everything is a scam. Wake up, it's not. I think we are obligated as humans to help out our fellow man. A boost really is not that much to ask. If you feel uncomfortable helping him out personally, at least phone someone, hell, even the cops. They usually help out as well if nothing else is pressing. nothing is worse than having trouble and knowing that noone will stop to help you. Been there a few times.
