HI, Your very correct in the most basic respect issue to another Human, Let them know if the schedule has changed, simple, basic.
No it's NOT just a Dutch thing, basic business protocol should be a quick message that an appointment has changed.
I think as I'm new to this DTube community, it's extremely supportive, however, I hope that the Global community sticks together for the long term and focus on the synergy, Thank you for discussing the non notification issue it this video. Regards, Rich
