closing before time

i have been getting a bad service from kfc in attlyn in the sense that if i ge there 15 minutes before closing time they will tell you what you want on the menu is finished, although no sign is up there to say its out of stock what i kniow about the closing time is that anything i want should be made available until closing time and not before you close ant at times the store closes 5 minutes before time which we all know is wrong and should close at ten not the time the employees feel is appropriate.
