Is The KFC on Greyston Halaal

Last weekend my boyfriend and I went to Greyston drive KFC. We went threw the drive threw and ordered two burgers, because KFC does not make pops and crunch burgers late at night. We asked the lady is this particular store halaal certified. We were told it was. However my boyfriend had a suspicious feeling. I went into the store to check for the certificate. It was no where to be seen. I asked a staff member. I got a rude response yes its halaal. I asked where is the certificate, I was told its in the office. What is the point of it being in the office? <br> Because we were unsure if its halaal or not, we had to give our away.
