Berry was shocked in Rio because ______.

Jason: Berry, you’re just back from Rio de Janeiro?
Berry: Yeah.
Jason: What was it like?
Berry: Well, the first day in Rio was quite a shock for us. Here it was a lot of fat middle-aged Europeans and Americans exercising along the beach, sunbathing, walking with their walkmans. It’s a big contrast to the thousands of people sleeping on the street during night.
Jason: What was the weather like?
Berry: The climate is very different from other places such as Peru or Bolivia. We were at sea level, and we all felt very good about it. No one of us needed to breathe extra air from time to time, and the temperature is about 25 degrees and the air is very humid.
Jason: That’s really nice.
Berry: The first day we had very nice weather, and were able to really relax on the beach. After these two days we had bad weather, rain and cloudy. So, we’re a little bit disappointed about that. Due to the weather, we explored the old part of Rio.
Jason: How about the food there?
Berry: We ate at local restaurant. Tiffs restaurant has a fixed fee of about US $10. Then you can eat as much as you want from a vast and delicate buffet consisting of both seafood and meat. Dessert and drinks are not included.
Jason: It’s been really a nice trip.
Berry: Well, Rio was not the experience we had hoped for, and we feel that this city is over-publicized. But anyway it’s cool to have been there.
