I have been hurt twice when "helping" people in the fast, with their rock collections. Unless the person is very old, or has some sort of physical issue (broken arm or whatever) When asked I just simply and plainly say, "no I cannot". On occasion I have been called names, and I then explained why I do not help normal and healthy seeming people with their bags. One time some idiot cursed me out when I refused an attractive woman's request to get her bag down, then as he got the woman's bag down, and it must have weighed 70 lbs. He sprained his wrist, and it dropped to the ground with a large bang, I said, "told you so" now who is the xxxxx??
