Brazilian on bare table?

Greetings esthies! I’m a massage therapist who shares a room with an esthetician. She and I had back to back appointments, so I happened to be in the room while she was cleaning up. She had given a Brazilian to her client, and I noticed she did it on the bare table using no sheets or protective covering whatsoever. She did wipe the table after the procedure, but I couldn’t shake that this could not possibly be in accordance with sanitation guidelines. I was a little mortified knowing this is happening on the same table I’m massaging on. Could anyone provide some information about best practices and if this allowed or not? I am prepared to take this issue to the owner of the establishment based on the responses I get here. TIA!
