I have no problem with sharing a table if it was pre-planned (i.e. eating at Teppan Edo), but otherwise I would probably be one of those people taken aback if someone asked me to sit with them or tried to join my table at a CS restaurant. I am a little on the shy side (though my husband would invite the world to sit with us) and when I sit down to eat it is kinda my downtime from the Disney crazyness. Plus, at some restaurants others may be offended by all the oohs and aahs I make while eating a good meal
