went to one of the local indian casinos for the buffer (great price
and good
food) and notice that the floor seemed to be springy. It's an all
concrete
building and I was trying to explain to my friend that it shouldn't
be that way
but she insisted that it was to help resist earthquake damage.

went back and forth so she made me ask around. how do I explain that
her logic
is wrong...or is it?

Some buildings are on springs.

Also some carpet has a springiness to it so it makes it easier to
stand on longer. Perhaps some non-carpet floors are like that too?

The difference would be if you just stood there and noticed movement,
then earthquake springs...
