Re:hot dog cost
The true cost of a Hot Dog is determined by Customer Satisfaction, repeat business and word of mouth advertising.
An inexpensive dog can COST you a lot of sales and repeat business.
Decide how you want to be percieved and then buy product to reflect that perception.
The old Addage, "Quality is remembered long after price is forgotten" is true. Give people value for their money that way you can charge a little more and they won't mind paying your price.
