My money is not worth it

Today at 7:45 pm i went to Caltex garage on Dobsonville ext2 , i waited for my turn to be served however the petrol attendant decided to attended to a person who came after me. When i told him i came before the guy he is serving he told me i must wait while he attends to this guys first. I thought it's a first come first service not based on friendship or gender based. I left the garage without being served and the petrol attendant didn't bother him that I'm an unhappy client. I WILL NEVER AGAIN USE CALTEX TJEIR SERVICE IS ****!!!!!!!
