Bad service

I visited the Wimpy in Gateway yesterday afternoon, it was the Wimpy at the Woolworths entrance. I ordered the streaky bacon breakfast and upon receiving my meal, I had noticed that the eggs were extremely oily and there were a few fibers in the eggs itself so I asked our waitron, Nelly, if it could be redone. Not even 2 minutes later, the plate comes back. The eggs are still oily and the fibers are still in the eggs, it looked as if the kitchen staff had just moved the eggs around, but nothing was redone, I was simply given the same unsatisfactory food so I requested the order to be canceled. Nelly advised that she was going to get the manager because she didn't understand my complaint, however there was no manager in store at the time. While I was awaiting the bill, the manager comes to our table without greeting us or introduction, she merely stares at us without advising why she was standing there. I explained my frustration to her, she apologized and advised that Nelly was a trainee, I then asked her why was Nelly was attending to a table on her own if she was still on training. This is unacceptable service from the manager, she definitely needs to get her act together. Although Nelly seemed to have been pushed into the deep end, she was friendly and tried to be as helpful as she could with the lack of training which she seemed to have. At the end of it, I ended up leaving without eating any food because of the terrible service
