Receptionist: “NO!”

Me: “…I’m sorry?”

Receptionist: “NO! The person in charge of that is on leave! She’s only coming back on Monday!”

Me: “So, when do I come in? I have a letter telling me to come on Monday the—”

Receptionist: “NO!”

Me: “I have the letter right here.”

Receptionist: “NO! What’s your surname?”

Me: “It’s [name].”

Receptionist: “You come on Tuesday.”

Receptionist: “NO! She has to explain to you the rules, and you need time for questions. NO! It will not take five minutes.”

Me: “So… maybe fifteen minutes?”

Receptionist: “Yes, fifteen minutes should do it!”
