Why would they choose to illustrate the cover of this pamphlet with a couple in the grocery store?

To be clear, “discharge” in this context means leaving the hospital, not discharge from the bladder after the cystoscopy, but still. Are we supposed to infer that the couple are discussing their cystoscopies in the produce aisle?

Let’s play a game. What other random images could they have used?

(For anyone who doesn’t know, a cystoscopy is like a colonoscopy only they put the camera up the urethra into the bladder.)
