I booked to go to a theatre show for the team I manage for our Christmas night out. We all agreed on the show and I'm sure they would have all been aware of the cost when they looked and agreed on the show.
I was expecting them to sort the money out that night and transfer the £20.
not one person has mentioned the money.
If your boss had booked a show for a Christmas night out would you assume it was a present or would you have been like “thanks for booking, here’s the cash”
