Precious water

I wonder what special water they use that they think it's reasonable to charge rm9 for a cup of tea. I'm pretty sure they use regular tea leaves which cost maybe rm 5 a tin and they can make up to maybe 50 cups with that one tin. Then there's electricity to boil the water which maybe like 2 cents a cup or even less. So it must be the water that's expensive. Oh, wait, I forgot bout the cup itself. Ok maybe one cup might cost rm10 but if u buy in bulk, u'll get at least 20% off. Then of course u reuse the cup so the actual cost of the cup is only rm1 if it's used 10 times. I'm sure they reuse the cup far more often so it's less than rm1. So u see, it must be the water then. Maybe they sprinkled tiny gold dust in it. If they did, it didn't make a difference to the taste. Still tastes like regular tea to me!
