Table hogs are just about as bad as chaise hogs. If not worse.
I think the crew should have their collective eyes open for tables, especially for families.
There are plenty of lounges around the ship where people can go to read their books.
On the upside, I think there are plenty of cruisers who, if noticing people with trays looking around for a place to sit, wouldn't ask, "Would you like to join me? I'm just reading a book."
