Waited 10 minutes and no one helped me

I drove into the service station and waited for someone to put petrol into my car but there was no one in site. I waited and waited. Eventually 3 more cars drove in. When I looked again all 3 of them were being helped but not me. A bit later I started my car to leave and a guy came and asked me what now. I said to him how long I have been waiting and that I was there long before the other 3 cars and he just said \oh sorry"and then walked away. I left without petrol and had to look for a different service station to go to"
