What you say is the truth.
Many players base their whole schedule of the day on the time of the match.
If they're playing at 1:00 p.m. in the afternoon, that means they can sleep in late, have plenty of time to eat, and then hit some balls an hour or so before game time.
If they have to play at 11:00 a.m., then they must rise and shine a little earlier, eat, and then get limber enough to play their 11:00 a.m. match. Most players like to hit some balls around before they begin their match to get in stroke a little.
AND of course, they must put on their tournament attire to play, hard shoes, belt, collared shirt, et cetera.
The majority of players I know run back to the room as soon as their matches are over to put on some more comfortable shoes and clothing. Not many of them walk around in their tournament attire, mainly because it is not as comfortable, especially the shoes.
A shoe manufacturer needs to come out with a comfortable pool shoe that is leather and acceptable at tournaments.
Oh, Nike, are you interested in becoming a pool industry member?
