durban brewing co pricing

when has it become compulsory to have ice with your drinks.durban brewing co. at on point cannot pour a fill glass of gin without ice. if without ice then you will receive half a glass of gin or less.i dont mind this,but imagine paying for half a glass of premix gin at R49.00(FORTY NINE RAND ) FOR half a glass. were is the honesty.Durban Brewing makes the price and determines how much they fill your cup.thats so funny.
