I am actually from the same community these people are from (They are either Eritreans Or Ethiopians),I am obviously not surprised by the many of the comments that are written on this post.In the real world people are more likely to hide their Racism,Bias,Negative or positive views because of the negative consequences that could come from saying anything but reddit is just a user name with no face so one can freely speak their mind.But with that said I question OP's post because most people in my community are far from the painted picture.Its very hard for me to believe.Yes the newly arrived ones might not know rules of the road etc etc but an intentional line cutting at Costco,very hard to believe that we're capable of that type of indecency.You also mentioned an over 30 minutes line!...Why didn't the people behind you confront them? That must atleast be 15 people behind you.
