A real shortcut or perceived?

I went into a restaurant last night and the waiter said ‘One’, with a finger in the air like ’table for 1’; without seeing my response he took a menu, directed me to a table. ‘I’m here to collect a takeaway order’, I said.
He took me to the counter, handed me the takeaway menu, opening it and pointing at all the tasty choices. ‘Thank you. I’ve already ordered via phone so I’m here to pick up.’ ‘Oh, of course’, he said.
Three assumptions: Dining in, dining alone, need to order.
We can see a lot of the same kinds of situations at work which can lead us to the perceived shortcut of assumptions. It’s more effective and human to pause assumption and go with what people present you with, what the need is right here, right now.
This is relevant for leaders in conversations, meetings and workshops.
Don’t assume people will move or change at the time, speed or direction you want. That’s an old outdated mindset of control. Rather meet them where they are and go from there.
This is the newer mindset of facilitation. Contemporary, collaborative and effective, the Leader as a Facilitator. Give a like below; what's your experience with assumptions.. or takeaway?
