Unacceptable attitude

We visited the Palm Valley Engen at 19.15. We aked the petrol attendant to fill up for R100....he proceeded to FILL up. We stopped him when we realised he was already at R300. We did not have the funds to pay and were referred to the supervisor who had a VERY bad attitude. He asked for a license and my boyfriend provided a VALID temporary license that was issued in cape town as his wallet was ****** there. The supervisor refused to accept a legal goverment document and called the security company. I will not allow being treated as a ******** for the attendants hearing impairement?! Disgusting. I have fuel rewards with a different company and insist on visiting this station because of their impeccable service. No more. Will never set foot there again
