"From next month on I can get a fixed day to meet you, what days would be fine for you?"
"I can make changes, in my week schedule. Anything but a Mondaymorning will be fine."
"In two weeks I will let you know what options there are."
... two weeks later ...
"I can get a fixed day for you, on a Mondaymorning, other days are impossible, because I wanted to give in to the preferences of my colleagues. There is no other option but this."
"Thank you for understanding that Mondaymorning is the worst possible option for me"
"Yes, but I really wanted to please my colleagues."
