Yellow?

We took a day off to recover from a sore neck, sore knee and sore bum. Also, we want to spend more time planning a route using that WiFi spot.

We've noticed that Argentinians are pretty stoney faced people. You give them a smile and get nothing back. Shopkeepers aren't in any hurry to sell anything, either.

The rain  (new word: lluvia) has cleared and it's back to being bloody hot all the time and we have to be vigilant for sunburn. We're also getting used to taking on lots of water. The town has cunningly put in place three identical parks, ensuring  we get even more lost in their one-way system. The fiends!

We had some cold drinks at a cafe and when theyr arrived, the waiter asked: yellow?
We were mystified. What does he mean, yellow? yellow? why yellow? He repeated the question: yellow? yellow?. It was guest at the next table who explained: hielo = ICE.
