I've been in US for 15 years and lived in Pleasanton for 6 years and think it's one of the best places to live.
Today I had a very rude experience - I was shopping with my mother in law at one of the retail stores. An old lady was being a bit rude to my mother-in-law and soon she told us to "go back to your country". When I told her this is my country too - she asked me to prove it and threatened to call the police. I told her to be my guest and that we will wait right there for them.
Anyways, she left never to come back.
I believe Pleasanton is a great city and I've never had this experience in my life before. I will chalk this down to a random incident by a random person - there are odd balls all over the world- and not a reflection on our wonderful city. However, it did spoil the wonderful mother's day I was hoping to provide my M-I-L.
