Fly Eggs

We ate at this restaurant yesterday. Spent R386 on a meal for 2 people. On our first serving my husband found FLY eggs on his pork slices that he just received from the buffet. When he took it to the owner tilo show him, the owner said it was carvings off the pork. I have taken a photo. What pork has pure white/yellow oblong shavings? Pork has fat and fat is see through. And then it begs the question...how did the 'pork shavings' get ontop of the gravy my husband covered his pork in AFTER it was carved??? its FLY eggs! And tgen the owner scrapes the eggs off and sends my hubby back to his table with his same plate of food and doesnt look at us again. No apologies, no acknowledgement....NOTHING!
