Cross Contamination is Unacceptable

I am upset and disgruntled with your benmore centre Branch. I have just been to the store and ordered chips. As the chips was coming out the Oil I saw the lady remove chicken strips from the same oil. I asked her do yourll make the chips and chicken strips in the same oil and they looked at me all buffled. thereafter the manager comes to me and I ask the same question. The lady tells me they were told to fry chips and Strips in the same oil. PLease can you advise how is that acceptable advise. There can be vegetarian/ Kosher/ halaal customers that might come in for JUST chips. You cannot sell chips thats been used for Chicken or any meat products. thats deliberate contamination. This was going to be my first try chips at your franchise and now I will Never purchase anything. That type of food prepation is unacceptable
