Opening day at Costco’s Shanghai store, its first in China, on Tuesday; many shoppers were there for good prices on familiar U.S. brands. The crush forced Costco to shut its doors just after 1 p.m., eight hours earlier than scheduled. A phalanx of police and security guards blocked people from entering, and some were still trying to get in as a light rain began falling at dusk. (There was a) two hour traffic snarl near the store before midday.  Other shoppers said they encountered elbowing for sale items, long checkout lines and a 20-minute wait for the toilet.  (Source: wsj.com, August 27, 2019)
