When I was still in college, after school hours just before going home, my friends and other school mates will be buying a hot dog sandwiches in a small stall near our main school gate. The vendor makes good tasting hot dog buns and filings that if you get there 30 minutes after the school bell rings for dismissal, there will be no hot-dogs left for you. On my last year in college, the vendor moved to a different state, we missed our afternoon hot-dog treats. So when I graduated from college, my friends and I have decided to set up a hot-dog sandwich business, hoping it will have the same result as the older version. And it does, the secret is consistency in the quality and amount of servings. You cheat a customer in one incident and it will result to a huge loss in your business in the long run.
