How do you react to seeing people makeout in the movie theatre?

Over the weekend my boyfriend and I saw a movie. I wanted to sit in the very last row, but it was already filled up.. the only empty seats were the first couple rows. So we sat in the very first row. The arm rest was up between us and we were cuddling... however as the movie went on, we got very close and ended up making out. Things heated up very fast.. it was a heavy makeout session throughout most of the movie. As we were doing this, we were pretty slouched down in our seats so I don't think people could see us... maybe they could? Anyways, how would you react if you saw people making out in the first row of the movie theatre? Would you not care and continue to watch the movie? Or be totally grossed out? Maybe even turned on? Ha.
