These birds have a free reign here
The birds are picking up any leftovers from the tables that they can lay their eyes on. The staff here seems to have reached a kind of understanding with them. They do not seem to chase them away at all. When a guest leaves the table, the birds will swoop in and pick at the food left at the table. Eventually, the staff comes to clean the table (whatever is left by the birds of course). They make no attempt to shoo the birds away. The birds, in their turn seem to acknowledge their need to clean the table and kind of hop away with that attitude of “Oh! You are here? No problems. I will move a bit.”
Surprisingly, for all the food that they eat, they are remarkably thin. This might have something to do with the fact that they kept stealing the sugar-free sweetener packets and peck at them till they got into it while carefully leaving the white sugar and brown sugar packets aside!!
