No cool drink sir

Today I walked into KFC (Town center, Mitchells Plain). My girlfriend ordered a Tower meal and I ordered a zinger burger meal. After ordering the cashier told us that there are no cool drinks to go with our meals. So I asked her if we are paying the same price for the meal, with a smirk on her face she said yes. Thinking to myself this is outrageous and I asked to speak to the manager and the cashier came back with a 2ltr Coke that was opened and said "the manager said this is the alternative, I'll pour some in a cup. It's the managers coke. " I was utterly disgusted in KFC, I walked out because the language I was about to use was vulgar. I'm disappointed and disgusted at KFC staff for treating their customers this way.
