Reminds me of a remark my 10 year old son made to the doctor 30 years ago when he went for a strep-throat retest. He knew about the visit + whatever else charges, so he said, "I'm not here for a visit, just a strep-throat test." I don't remember the doctor's reply or the billing situation but will never forget my son's interest in the $. He went on to major in economics in college!
