Being Not Received at Reception Desk

I am thrilled to only see two people ahead of me at medical clinic No one is at reception’s desk I know the routine so I fill out the forms while I wait No one comes. I have been here four minutes I ask one of the others “was anyone here?” “She left a bit ago,” one replies. a female nurse comes out of exam room. Fiddles around a bit. Goes back into same exam room. Nurse comes back out after a bit. Asks me “where is the receptionist?” “I am wondering myself,” I reply. “she will need your ID and medical card,” the woman says. I hand them over and she leaves it all for the receptionist under the high counter. a few more people leave exam rooms. No one else is called back yet. a woman holding a sandwich and large drink comes wandering in. That explains why she had left her desk. But to not leave a sign or anything? I remain standing there, not wanting the six people behind me to get ahead.
