I’m not sure whether it happened at any other tables. I went to the table for my precinct/ward (apologies for any imprecise language), and there were three workers, if I remember right. One of the first two would ask for your name and give you the roll to sign.

Then most people seemed to proceed to the third worker, who (again, if memory serves) had a pen and notebook and was asking voters for their affiliation.

A voter ahead me in line took issue with it, which seemed to annoy the worker. I did not catch the explanation of the reason for that question, but the voter’s response was something to the effect of, “Well, check your book then.”

My only real hypothesis was that it was a weak attempt to catch impersonators, but that doesn’t seem a very satisfactory answer.
