Taiwan is convenience exemplified. As in Japan, convenience stores abound in Taiwan. Within a block radius from Angela's apartment are at least two 7-11s, one Family Mart, and a Niko Mart. Not only can you dash into a convenience store to pick up a drink or a hot dog, you can also pay your utilities bill. Simply present your phone bill (they come printed with a bar code) to the cashier, hand over the money, and you're set!
Random note: while schlepping myself over a good portion of Taipei yesterday to apply for an Alien Residence Certificate, I noticed that just like the U.S., Taiwan's police officers drive Ford cars. Huh.
