A coach and a trainer are one thing: one record, one resource on the booking grid, one path.
Coach
Two switches, not one: the coach's status, and whether they are available. Booking needs both.
A coach's time is booked on a resource of its own, exactly as a court is. There is no coach without one.
A training session takes the coach's time and a real court together, or it is not booked at all.
A coach's phone number is never shown to a player, and contact goes through the app. There are no ratings and no reviews in this version.
The club pays the coach outside Sinjab, on whatever terms they agree. Sinjab settles a training session like any court booking: the club collects the session fee and Sinjab takes its usual share of it. Sinjab holds no fee for the coach and owes them nothing.
The coach's price list
A price per length. A length with no price is never offered to a player at all.
A split session is always halved, however many players there are.
