Before coming to Japan, I read a very small book about eating in Japan. I bought the book in Little Tokyo in Los Angeles. Here is the new edition:
I learned that at restaurants, if you are a good customer, they give you freebies. Of course, this is true in most countries. I had been a college student with no extra money for restaurants. Now, I was working and had some extra money. Restaurants and freebies were a great combination for me!
I was working in Osaka at that time. And, I found a pasta restaurant that I really liked. The third time that I went in the staffed thanked me for coming back. I finished my pasta and the manager put a cappuccino in front of me and thanked me, again. I was in heaven—a freebie! What Wonderful Service! I went to that restaurant once-a-week and always got a free cappuccino!
Have a good one!
