Oil used to fry veg and non veg at Wiesenhof LCM hospital

Bad experience at Wiesenhof at Little Company of Mary Hospital. I told the waitress I am vegetarian strictly and was limited to order chips and salad. First taste of the chips told me the oil used was used to fry non veg and the manager who was very understanding immediately admitted so. Vegetarians be aware and ask if chips are fried in separate oil.
