The worst experience ever

There I am wanting to fill my tank at the shell garage at 14 Avenue number 1 waited for some assistance for 5mins and when someone decides to come I ask them to fill my tank slowly he asks why shook as I am I say because I want it that way the petrol attendant turns and says Voetsek to me shocked as I was I asked if his saying that to me I asked for a manager , the manager turns around he says he apologizes on his behalf but the petrol attendant kept being rude and to top it all he was drunk he reeked of alcohol I’m disappointed
