"Bubbler" is actually more of a Milwaukee/SE WI term; over here by Madison you're far more likely to hear "drinking fountain".
I answered the questions as if I was around 20 or so, before I moved "back" to WI. For example, nowadays I say "soda" but back then it was "pop".
I went back and re-took the test and answered "soda" this time. Interestingly, the questions *after* that answer changed and my 3 cities then changed to Rockford, Madison and Milwaukee, which is far more representative of the current version of me.
