Anyone remember taking B&B owners children out for the day?

My parents who are in their late seventies say that when they went on holiday as children and stayed in a B&B, their parents, and other families would take the child of the B&B owners for the day. They say this was common as B&Bs then were full board i.e. provided three meals a day, so visiting families recognised it was a hard life for the owners and they rarely had any time to take their own children out for the day. So the children would be taken out by friendly families who were paying guests.
Anyone else remember this? Of course it would never happen now.

My mother talked about one child her parents took out for the day was was very badly behaved. They never took that child out again.
My mother's parents would take her to the beach, gardens, fairgrounds, for fish and chips, etc. So it wasn't cost neutral. I have no idea if the B&B owners gave my grandparents money for this?
And were they all called boarding houses? I thought that was when people lived there permanently, although I could be wrong.
My grandparents were not the type to go back year after year to the same place, so the owners could not have known them that well. My grandmother was very into being respectable though, so maybe she was seen as a safe pair of hands.

Not a B&B but a hotel we stayed at over Xmas in the early 80s.
We took the youngest daughter along with us when we went out for the day. There were already 5 of us kids, so another one in the boot of the estate didn't make much difference!

@TheOrigRights that sounds like the attitude my grandparents had.
