Hairy food

Me and my husband went as a treat to picanha's we ordered food and while I'm stirring sauce in my food, I literally pulled out a long hair, so I asked to talk to the manager , infront of me and my husband he did give an apology but in the same breath he tells us it's a mushroom hair which I by the way know how it looks in food.......... dont try to cover up rather just own up to **** that happen, we will never go back to that place and people look for hairs because if they cant own up to that then it means it happens often.
