What screams "poorly educated"?

Writing long word salads and looking down on people who can’t speak English like they are straight out of Oxford.

Throwing their garbage except in dustbins.

- Throwing trash - Driving on wrong side - High beam - Honking the moment signal turns green - Shoutingly talking - Being a chapri - Excessive mobile usage - Not sleeping / waking up on time

Judging someone by their looks

People who are very impatient while standing in queue and also cuts the queue. Woh jinki Baap ki road hoti hai. Who talks to waiters/servers in restaurant or shops in ill manner.
