BAD ATTITUDE /BAD SERVICE OF ALL STAFF AND SUPERIO

I work for a very reputable airline and i am forever wearing uniform so i will never ever be rude while in my work space but it bothers me that KFC staff feel its ok to drag the KFC name in the mud with their bad behavior and service all the time , I have had countless run ins with how they treat their customers, this morning i went to buy a sandwich and the shop was still closed at 7:10 but when i asked what time they open they told me 07h00 . This morning , one of their staff comes out of the shop to do her own thing , i then greet her and she just looks at me then i could tell she was in her usual ''KFC MODE\ , so i just asked her what time do they open and she rudley said \" i dont know \" then got up and left me standing there, this is not the first incident and i'm sure it wont be the last, just last week, i bought the 3 piece streetwise and was given two pieces, i went back to say \" guys i'm one piece short here\" , i never got a sorry or anything, the lady just took my meal ,added the piece and said \" next \". i FEEL SO DISRESPECTED because whenever you ask for a supervisor you are told \" he is busy\". i am a regular customer and they feel they are doing me a favour each TIME"
