The shul I attend has some members who are not fully observant who drive there. One of them is an elderly gentleman who walks with a cane. This past Shabbos, he dropped some of his change on the floor (which is muktzeh). He was determined to retrieve it all himself. But I thought it would be a hazard for him to bend down and pick it all up, and I did it for him. Did I do the right thing? No one else seemed to notice.
