Well at least you got a great story out of it - the paradox that you describe yourself as a pussycat but had to force this man to action by physically blocking his truck, good on you. But then the cherry on top was that after you had to help move the bags you still had to give him a large tip one that has quadrupled in five years! Fascinating.
And another detail, heretofore undisclosed, that I think you'll find even more interesting, is that my two strapping, male siblings slept soundly through the entire episode:)
