Dress code needed to buy at kfc.

Today I went to kfc with my wife in jouberton at tower mall, I went in ordered my food after receiving my food a strange guy approachs me after 10min to 15 mins of being there and tells me I can't where pj's inside, this guy is the security in casual clothes to start with really after 20 years of being a customer today was the first time to hear that kfc wants a dress code to buy food, there is no sign that states that we should not wear pj's inside, worse part the security that's not even in uniform is standing and talking to other guys who is drinking alcohol in front of the door as if it's a shabeen, kuthwano the Supervisor /manager explained to me and I told him to put up signs for the dress code so customers can comply.
