Most OW airline operated lounges have "manuals" on lounge dragon desks, with very detailed explanation of access policy and an explanation of what to do in each scenario,as well as images of ALL OW cards. Non-OW lounges (third party lounges) operate, as directed by airline staff at the local station, because those lounges don't have to comply with OW lounge access policy.
