Why do Gujratis have no manners?

While waiting outside a restaurant, a group of 7-8 Gujju women ( of 3 generations) came and gave their name in the waiting list. They looked posh, all of them wore diamonds and came in cars with drivers. They stood right in front of the main door and blocked the door. Then proceeded to stand in a big circle, completely invading my family’s personal space ( felt like I was in Dadar station) and spoke loudly. Now there were around 30 people waiting outside the restaurant before they walked in, and NO ONE behaved like this. Money cannot buy gujratis class ever.
