Staff unfriendly and no service to me

I stopped at Engine Service Station to put petrol but staff not even worried about me as i was waiting to be helped, But no one help me they walked past me than as i wait i see no one approaching me. i got out two taxis and a white merc came in they were helped asap. so i asked one guy passing me twice why are not helping me he siad he did not see me. than he walked away. i was never treated like that. before but at this place i did not expect. i was really disapointed. i waited about 7 minutes in total. the staff not worried. they talked to eachoter and take their own time. please people where is the service. as i was standing there i saw something amazing they only helped first who they know well, if you rich and muslim they help you. they helped all the guys who had a head covering and nice taxis muslim people which is wrong.
