yes, that was how it was supposed to sound
When you read Trip Reports on the part of european first timers, you'll often read things like "The americans are crazy, they set their A/C too low, it's colder in their buses/buildings than in my deep freeze"
it's part of some of the misconceptions that people have. But it's also true that many of us, europeans, do catch colds, or even worse, because of the A/C.
I guess that spending a full week in bed with a fever because you caught a nasty cold on a bus does qualify as "dangerously low", and you'd be amazed at how many people actually fall ill because they're not used to A/C.
