As school children though we 'got' the message. Or should that be we 'received' the message.
There are times when got is better IMO.
E.g. Your sentence or He got his just desserts!
If I asked a year 1 ^What have you got in your hand? The answer would be quick.
If I asked What are you concealing in your hand? the answer would probably be “What?” I then have to say, “Don’t say what, say pardon”
The last part of your post has reminded me of something from my primary school days, when I was about nine.
A member of staff came into our classroom and announced, "I have a job for someone" (or words to that effect - it might have been "I've got a job for someone 😁)
One of the boys said "What?", and was sharply corrected by our class teacher with "It is pardon, not 'what'".
It was quite clear to me that the poor boy had not wanted the question repeating, but had wanted to know what the job was!
You can see how angry I felt on the boy's behalf, given that it still bothers me nearly sixty years later.
