Why?

I'm watching some tennis, a tournament from Florida, and I have a question.

Why, do the tennis players have to carry and lug all of their equipment when they come on to the court. Golfers have caddies, I think that every sport, the participants don't have to lug their own equipment around. I've often wondered, a tournament, the winner just won a couple of million dollars, lifts that heavy bunch of equipment, throws it over the shoulder, and carries it off of the court.

At the start, I would think they would want to conserve all of their energy, arms and shoulders are important, why lung all that heavy stuff around. Can you imagine Donald Trump, or Bill Gates getting out of their limos and carrying their own luggage into their two thousand a night hotel?a

If I was a world class tennis player I would pay someone to carry all of my equipment, last thing in the world is to wear myself out lugging all that stuff to the court.

Interesting Farm Facts

98% of farms are owned and operated by families, but these farms impact more than just the people working on them.
Farmers have business interactions with many businesses in the community you may not realize.
They work with local feed mills to obtain food for their pigs, accountants to make sure all business transactions are in order, purchase equipment and seed to produce grain, as well as fuel, tires and parts for vehicles and equipment used on the farm, not to mention the building materials for the barns tehmselves.
All these interactions stimulate the local economy and provide jobs as far away as the store in Japan, where the final product may be sold.
