Honestly, I spend half my money on beverages. At every meal, the beverage part of the meal costs more than the food part. Everything is so cheap. For example today for breakfast I had fruit with granola, yogurt and honey (20Q), coffee (5Q) and water (12Q) (My hostel is 25Q). And I drink a lot of water. In Mexico in hostels you could fill up your water bottle with the big office coolers, but here it seems that it´s normal to buy it in plastic, which is more expensive and bad for the environment.
