I had a similar experience getting some fancy guppies at the LFS today. The employee helping us bumped the container that was holding the fish we had picked out. One guppy dropped a good 8 feet (the guy was on a ladder) and landed on the floor. I saw it jumping around so I ran over, struggling to scoop him up. Another employee walked past but didn't even stop to help. Finally I got him into my hand securely and the guy that was helping us put the poor thing back in the tank.
I sure wouldn't want to have a fall like that (likely causing internal injury) and then suffocate to death on the floor.
