In my experience (every day for 14 months in the quiet section), some people don't give a rat's ass though, and ignore the signs and plaques. It wasn't uncommon to see/hear sub 10-yo kids there either, and woe unto you if you attempt to explain to the parent that they are sitting in a quiet section. The ultimate fault is of course on SJ for not making it more obvious that the booked seats are in the quiet section during the booking process, however.
