OK theres literally 100s of ways to get free chicken from KFC but here's one method I tried with a friend. You need another person with you to do this. 1) Order a box meal / any chicken combo (NOT burger!) 2) Your friend orders some wings (theyre cheap af here) 3) you go leave the store / or sit down if youre eating in. 4) swap your chicken leg/thigh/breast with your buddys chicken wings 5) go back in the store and complain that they give you chicken wing instead of chicken leg/thigh etc. 6) they apologise immediately and give you some free chicken as an apology They sometimes will ask you which member of staff gave you the chicken, I don't like snitchin' so I just say I can't remember. Easy peasy and takes about 60 seconds. I can post some more easy KFC methods if you like this one!
