It is hard to understand why you would call people to an event more than 15 minutes before the start.
The event should start on time.
In my opinion, it is not ok to call people at 9:30 and start at 10:15.
Another thing – ending a call prematurely and waiting for people who are late.
Let’s say you wait for someone who is late. You should extend an activity so that if someone else comes late, there is more time for the others in the end.
It’s not OK to wait for someone 10 minutes, then end everything abruptly due to lack of time.
