My personal experience on my last visit made me hate taxi drivers. They just like to rip people off.
On a more general view, these are things that i dislike about Pakistani people (especially in Karachi).
1. No smile and emotionless greetings.
2. Spitting and throwing rubbish anywhere without concern. ( Seriously need to ban chewing pan)
3. Being judgmental and looking down on people that are poorer.
4. Families interfering in everyone's lives.
5. Distorting Urdu and using Hindi especially bollywood gangsta words. (Sounds horrible and makes me so angry).
6. Bribe culture, people complain about other people taking bribes but instantly offer bribes to get their way.
7. Use of multiple measuring system (confuses the hell out of me)
8. Excessive use of car horns and driving with high beams. (I am sure this alone is a cause for everyone having high BP)
9. Being scared that what i am eating is real or artificial or worse could be dog/donkey meat.
10. Racism, everyone is racist, even my own family is racist and think that Pakistan is surviving because of us Pukhtoons. All that changes during cricket matches then everyone is "Our People"
Things that i like about Pakistani people
1. Respect for elders.
2. Optimism to change in the newer generation.
3. Finding ways to get things done or working again (Jugarh)
4. Social life. Doesn't matter what day it is or what time it is, everyone is ready for an outing.
5. Food, i was scared of what i was eating but damn it was so yummy.
6. Love for the country, even though people complain all the time about all the things wrong in Pakistan but their love for it is undeniable.
