In 1959, Harvey's introduced three original concepts in the drive-in take-out business. The first concept was for a customer to order, purchase and obtain a receipt, which was placed on the topping counter. The cash was immediately placed in the cash register, thereby controlling and monitoring cash, and keeping theft to a minimum. The second concept was to have the customer move along the counter, following his/her receipt, and then, at his/her request, have an employee "customize" his/her hamburger with a variety of toppings. The third concept — developed for its full-line Swiss Chalet restaurants in Montreal — was to purchase potatoes from Prince Edward Island, have the franchisee wash and cut the fresh potatoes into oversized chips with skin on, and then deep-fry and serve the chips on-site. This approach was a distinction between thin pre-frozen and pre-cut French Fries of unknown origin that were being sold at the time. Ten years later, under different management, the number of toppings was substantially increased, and pre-frozen and pre-cut string French Fries were introduced, replacing the freshly cut PEI potato.
