Au padel, you can only serve at or below the waist. The server can possibly bend his legs or not bounce the ball too much to avoid finding himself in an awkward position.
In general, when the fault is committed by the players, it is rarely sanctioned if a referee does not intervene.
It is indeed difficult for the opponents, for the server, or the partner to really sanction this kind of fault.
The consequence of a service that starts from too high: It is the speed of the service difficult to return then.
