Shell Canada gas station Shell Canada Unco-operative and rude cashier Richmond Hill, Ontario

All I wanted to do is to find out how much would it cost to purchase a shell gas station in that vibrant area in Richmond Hill. What I got was a rude and racist reply from this cashier by the name of Sam who works over there. He told me that it wasn't worth my money and that I should go back to the Philippines and make a living there. Being a generous and noble Canadian of Filipino heritage, I FIND THAT OFFENSIVE and do not forgive that man Sam who, judging by his accent, is of South Asian descent himself. He then told me to leave because I was taking up other customers time when there was no customer behind me and the area didn't seem busy. He then went to the back to ignore or call the police. So I left this despicable man. He looks like he's been doing that to other Filipinos who live in that area because I received a lot of complaints from my friends that he was treating almost every Filipino customer with disrespect. I want head office to investigate this man by the name of Sam and punish him severely by firing him or something.
