I remember the first time I realized water fountains weren't known as bubblers was back in the 80s on a field trip to slater mill I believe it was. I had asked an older couple where the bubbler was? And they responded in a British accent asking what I was asking for? I remember saying you know the thing you press the button to get a drink of water? The husband's response was the oh my, you mean the water fountain! Then laughed at me while pointing to the bubbler with a mocking tone saying g the bubbler is over there.
