what is the meaning of "like a stick of rock" here? [closed]

Solution 1:

You are right in saying that "rock" here refers to the confectionery. From Wikipedia's article: "These cylinders usually have a pattern embedded throughout the length, which is often the name of the resort where the rock is sold, so that the name can be read on both ends of the stick (reversed at one end) and remains legible even after pieces are bitten off." This is a distinctive, notable feature of sticks of rock.
