Isn’t That Just A Reservation?

I’m working at the front desk at a hotel. I get a call from a guest.

Guest: “Can I make a reservation for dinner at [Hotel Restaurant]?”

Me: “No. Unfortunately, it’s walk-ins only — first come, first serve.”

Guest: “Oh… Well, can I walk in and ask them to hold a table for me for a specific time?”

Me: *Face-palm*

The same person asked me if she had to order ahead of time at [Coffee Shop] after I told her it’s a grab-and-go coffee shop.
