Undomesticated Peeves

Individuals who take up an entire table (especially one meant for anywhere from four to eight people), especially when they don't have any apparent reason for it, for example, if there are plenty of smaller tables nearby and larger parties waiting for a table. Or if they clearly have nothing else to take up the space (like paperwork, homework, large bags, baby gear, etc.). There doesn't seem to be a trend for what types of people do this - I've seen people of all ages and both genders do this. The other day there was a petite girl in her late teens or early twenties sitting alone at a table for five, propping her feet up on the chair of the next table - thus taking up two tables and enough seating for seven people. The best thing: she was looking around nervously, as if she expected to be evicted from her seat at any moment (which wouldn't have been uncalled for since the restaurant was crowded to overflowing). Obviously she knew it wasn't... socially ethical?... yet she chose to ignore that and do it anyway. Fortunately, her nerves caused her to leave quickly.
