Since the typical fast food service worker see almost their entire paycheck go to living expenses before any opportunity for luxuries or savings, that does indeed sound like a crippling if not insurmountable financial burden for someone who incurs an x-ray expense like this unexpectedly. Especially since whatever reason they have for needing an x-ray could affect their ability to earn income from McDonalds. I don't think hourly wage work offers the same perks as entry-level development roles at facebook with regards to paid sick leave.
