They don't sell textbooks at school, they sell photocopies. Apparently copyright laws don't exist here.
It's actually a common practice to go to a sex hotel. You can rent them by the hour and they are all over the city. No, I didn't go to one, but I know someone who did!
Remember how I told you about the ice cream shops all over the place? Well, they deliver. As a matter of fact pretty much everything can be delivered; empanadas, ice cream, all restaurants, even groceries.
Doctors make house calls.
Windows don't have screens. They have these weird plastic sun shade things with holes that you can pull up or down on the outside of the window.
I'm sure I'll come up with some more for round 3...
