Bad management attitude and pricing of products

Day light *******ofrestaurants that think that they can take advantage n rob customers.....we had something to eat at the NetCare Cafe at Garden City Clinic....kids ordered cranberry juice but they didnt yave so i went and chose 2 lipton ice teas n noticed it was R14.90...when the bill came the liptons where charged at R25.90 each....when i askedthe Manager saysitsbecause we sat down and drank it instead of a take-away....my point is what justification is there to over charge and then the Manager laughs at you saying like it or not....this is unacceptable.....this is ecenomic manipulation n *******....waiting to address the issues with hospital management if they even bother addressing the matter
