Pork trotters with a thick layer of oil

Came here for some pork trotters, when it came I could smell strong oil which was not that pleasant!

When I looked at the dish there was so much oil floating on top!

 

 

The taste of the pork trotters were ok, but I didnt like the oil.
I put a fork into the sauce, and the layer of oil was about 5mm thick!
