Then during the 17th Century, the people of Tokyo came up with the idea of adding vinegar to the rice to give it the fermented
flavor without the bother of waiting a few days and in the early 1800's, a man called Yohei Hanaya began serving sashimi on sushi rice at his street stall. This was the beginning of the current style sushi.
The stall (or Yattai) was simply a wagon with a counter with curtains and at the time, the most popular stalls were the ones with the dirtiest curtains. Customers would eat their sushi, dip their fingers in their tea and then wipe their hands on the curtains to dry them.
Since the 1950's, sushi has been served mostly in indoor restaurants with a more western-style arrangement and nowadays, sushi in Japan is not served in a Yattai stall although they still exist.
