In a future when people commonly use teleportation to travel instantly to any point in the world, a sale at a department store might draw bargain hunters from all over the planet ... followed by reporters, pickpockets, political activists looking for a crowd, and anyone who think it might be fun to show up to a riot.
Someone reminded me of this today, I'd read it in a Niven short story collection years ago. He basically predicted the concept of a flash mob, though ours happen without teleportation and for generally silly reasons.
Laurence van Cott Niven's best known work is Ringworld (Ringworld, #1) (1970), which received the Hugo, Locus, Ditmar, and Nebula awards. His work is primarily hard science fiction, using big science concepts and theoretical physics. The creation of thoroughly worked-out alien species, which are very different from humans both physically and mentally, is recognized as one of Niven's main strengthsLaurence van Cott Niven's best known work is Ringworld (Ringworld, #1) (1970), which received the Hugo, Locus, Ditmar, and Nebula awards.

The creation of thoroughly worked-out alien species, which are very different from humans both physically and mentally, is recognized as one of Niven's main strengths.
Niven also often includes elements of detective fiction and adventure stories. His fantasy includes The Magic Goes Away series, which utilizes an exhaustible resource, called Mana, to make the magic a non-renewable resource.
Niven created an alien species, the Kzin, which were featured in a series of twelve collection books, the Man-Kzin Wars. He co-authored a number of novels with Jerry Pournelle. In fact, much of his writing since the 1970s has been in collaboration, particularly with Pournelle, Steven Barnes, Brenda Cooper, or Edward M. Lerner.
He briefly attended the California Institute of Technology and graduated with a Bachelor of Arts in mathematics (with a minor in psychology) from Washburn University, Topeka, Kansas, in 1962. He did a year of graduate work in mathematics at the University of California at Los Angeles. He has since lived in Los Angeles suburbs, including Chatsworth and Tarzana, as a full-time writer. He married Marilyn Joyce "Fuzzy Pink" Wisowaty, herself a well-known science fiction and Regency literature fan, on September 6, 1969.
In addition to his awards for Ringworld, Niven won the Hugo Award for Best Short Story for "Neutron Star" in 1967. He won the same award in 1972, for "Inconstant Moon", and in 1975 for "The Hole Man". In 1976, he won the Hugo Award for Best Novelette for "The Borderland of Sol".
Niven has written scripts for various science fiction television shows, including the original Land of the Lost series and Star Trek: The Animated Series, for which he adapted his early story "The Soft Weapon". He adapted his story "Inconstant Moon" for an episode of the television series The Outer Limits in 1996.
He has also written for the DC Comics character Green Lantern including in his stories hard science fiction concepts such as universal entropy and the redshift effect, which are unusual in comic books.
