That's the most hilarious double speak. I can only imagine the repressed artists getting told off for putting 5 slices of cheese on a foot-long instead of 4. "I was just trying to express myself, you said I was an artist."

I assume the "sandwich artist" title is an allusion to that old saying - y'know because they pay their employees so little that they're starving.

Everyone knows you spread mustard from right to left. We aren't knaves.
