Why international tourists find Japanese convenience store amazing

Japanese convenience stores have so much more to offer than typical convenience stores in US. They are found at a few minute walking distance from anywhere in Tokyo and other cities.  At these drop-ins or so called "Convini", Japanese locals can grab a bite to eat or entire meals for the day, photocopy documents, print pictures, pay bills and even a place to sit and eat. Affordability among others explains their popularity. Samuel and Audrey were pleasantly surprised to find out how much $20 could buy for lunch.
