Disappointing drinks

We visited Pizza News yesterday, Sunday 04 October. There were 7 of us. We ordered 4 pizzas which we all enjoyed. Pity we cannot say the same about the drinks that we had with our pizzas. <br> We ordered a 2L Fanta Orange. The staff insisted that they needed to pour the drink out into a jug to serve at the table. I have eaten in many fast food places but have never seen this before. Completely pointless. It tasted diluted and we doubt weather it was in fact 2 liters. We complained to the staff but they just shrugged it off. Most the drink was left behind. I won't be surprised if they serve that to other customers. What other possible reason would someone have to pour a 2L coldrink out into a jug?
