Customer is always wrong

Collected my vehicle from the Audi dealership at N1 City. Got there quite early coz I had to be somewhere else afterwards. Service lady Melissa David's saw me as I arrive, the receptionist even went to inform her that I was there. She made me wait 45+ mind before she attended me. Told me afterwards that I should not have come early coz she has other duties to perform in the morning. Utterly disgusted in her attitude and response. Our business only took about 5mins. The lady at reception and another guy there called her twice to tend to me and apologized several times on her behalf. Melissa did not even make an effort to apologise.
