Final answer:
When a burger or sandwich comes with fries, it means it is served with a side of french fries, a practice rooted in fast food history, notably with the advent of fish and chips during the Industrial Revolution.
Step-by-step explanation:
When a burger or sandwich comes with fries, it is typically referred to as being accompanied by a side of french fries.
This pairing is a common practice in fast food and casual dining establishments.
Taking a historical perspective, we see the influence of the Industrial Revolution on the availability and popularity of such fast food combinations.
The history of food, particularly fast food, changed dramatically with the invention of fish and chips in England.
This dish consisted of the less desirable parts of fish, such as tails and fins, fried together with potato chunks.
Heavy salting and newspaper wrapping made it a convenient, affordable, and popular fast food item among the working class.
It represents an early form of a meal accompanied by a side, similar to how a burger is now often served with fries.
