Perhaps the confusion lies in the fact that in the article it states that Rush was with Al Michaels. Perhaps they both left 1,000 tips. Thus the total was 2,000 but only 1,000 came from Rush.
I think the article is explicit that that is not the meaning.claims she received two generous tips of $1,000 on two separate occasions from conservative radio host Rush LimbaughDoes Al Michaels make Rush Limbaugh money? I doubt that there are many people who would try to match Rush in the generosity department.
