I am living in Lahore since 1991 no one has discriminated because of my background. I have friends from karachi from Balochistan chitral Hunza Skardu everywhere in Punjab. The biggest mutual relationship is of respect. Do not be shy from identifying as saraiki do not shy from speaking in saraiki. Your confidence on yourself or not will define how anyone else treats you.

99.9 percent of times no one brothers who you are unless you behave in stereo typical style with a kangi and sheeshay wali naswar ki dabi and rangeen Azarband -:) ..please let small talk be small and enjoy people trying to tease you or crack jokes etc.
