All Aboard the Cattle Train!
On our train which runs around the outside of the huge castle we serve tea and coffee in plastic cups. It is very expensive because people are captive once on a train and they seem more than prepared to pay for it so they deserve everything they get! And what they get is a vegetable fat milk substitute instead of fresh milk which we tell them tastes like real milk. (We even put a picture of a cow in a field on each of the little cartons). The passengers are more than happy to put this stuff in their tea or coffee. We also use plastic cups which melt slightly but save us money. There is no evidence that minute amounts of plastic harm a person but when you have to save money and deliver tea and coffee to so many people, its worth the risk.
We increase our prices by more than the rate of inflation EVERY year and these mugs still use our trains and drink our luke warm tea. If people are prepared to behave so foolishly, then there's no guilt on our consciences!
We get very few complaints although our trains are often late, are dirty and overcrowded. The reason is that many of our passengers are native Mediocritaxans and don't want to rock the boat or cause a fuss.
