Have you ever ordered a sandwich at Subway? If so, you may have noticed that the workers are called “sandwich artists.” Are they artists in the true sense of the word? Are they somehow expressing something when they put together the sandwich precisely as you request it? Instinctively, many of us would say “no.” Slapping cheese, meat, and condiments onto bread does not seem like the sandwich makers’ speech, especially when they are simply following the customer’s instructions.
