Dissapointed

I'm honestly disappointed by your service today, went to the nandos in Atholl Melrose, I got 4 1/4 chickens. I then told the lady that I want leg pieces she told me I wasnt allowed to choose, have the rules changed all of a sudden or she was clearly undermining me. I always buy from nandos and have never had such an issue. But honestly today was the worst service ever. I'm now stuck with chicken breasts that people are refusing to eat. Please fix this...
