Trump probably has a limo take him everywhere, a driver who opens the door for him, and "flunky's" who do all of his other beckoning.
Athletes, many of which are multi millionaires, endure all sorts of demeaning things they have to put up with. Sit on a bench, eat sunflower seeds and spit out the shells on the floor. In football, they put up with being ferociously tackled,, knocked to the turf, and having one concussion after another one, Retire with their millions, and then, forget how they made them.
In golf, at least they have someone do the heavy work for them, but not tennis, you do all the heavy work yourself. Probably, in Rogers case, tailor made clothes, startlingly white sweaters, probably cashmere, the most expense, comfortable, appropriate shoes, appropriate for the surface, and he has to carry it out to the court, and when done, back in. Why can he not have someone carry it for him?
"Here, Joe, carry this bag out to the court, play tennis, and when done, pick up this check for six million."
"Oh, Ok!"
