Normally any restaurants will have the following modes of operation:
– Customers come in to Eat
– Delivery partner like Swiggy will pick order for customers and deliver to their home
– Drive in, like in Mcdonalds where customers buy food from a car through a window.
“Billu Tandooria” located at https://maps.app.goo.gl/MY8G6iizhPfa49be7, mode of operation does not follow any of this. Here we can see an array of cars around the restaurant. in the evening from 6 pm to 10 pm, attached video. Blocking roads for normal commuters.

They have their own delivery boys who runs towards the car as soon as it approaches the restaurant. And takes the request for order. (Encouraging Vanity)
These cars are special because the drivers have their pet Dogs and cats hidden inside their cars. And they come here to actually feed their pets for free. The delivery boy is paid 10 to 20 Rs for this task. And the restaurant is fine blocking normal human customers for their food and giving preference to Dogs.
If so-called rich people cannot afford to buy food for their pets, they should quit raising them. In this world humans are competing with Dogs and Cats for food. Only because of people like customers of “Billu Tandooria”
