Sharp plastic found in Lamb curry

On the 31st of July my fiance and myself were dining at the Restaurant Jeera in Suncoast. Less than 5 mins into my meal i had discovered a sharp plastic in my mouth..initially i assumed it was a bone,however after closer inspection it was actually a sharp plastic. We were horrified..this could have caused a possible injury too me internally if i had ingested it. I spoke too Mr Werner du preez regarding this incident he was quite apologetic and helpful. As for the supervisor Rita she is rude and very ill mannered too be working with customers. On a different occasion 3 days prior too this incident she cleared our table whilst we were still eating without even asking if we were finished.When i greeted her lastnight she looked at me,smiled and ignored me. The staff at the buffet area do not even know what dishes were available,when asked simple questions about the food ,she ignorantly looks at me and tells me shes from the cold buffet and not the hot buffet..so what was she doing at the hot buffet then?? These people are giving Jeera a terrible name!! Being a businesswoman myself i think the staff should seriously be trained or replaced. I will not return there again.
