Friday because of the Japanese school finishing time, 2nd class can only open 6:00 thats why there is 30 minutes gap.
1st class(4:30 -5:30 ) is for kindergarten students.
The other venue they will give us these gap free because those reasons.
In this case, could you give me kindly let us stay and start 6:00 and not count half an hour cost, please?
Of course some kids turn up early may start kicking the ball in those time though..
