A solo diner goes into a restaurant without a reservation (before 6:00) and asks for a table for 4. She sits alone for 20 minutes, during which time several servers come by (one at a time) to ask if she wants to order anything ("perhaps an appetizer ?"). She declines each time, saying she is waiting for her friends. She also indicates that she doesn't know when or if they will arrive. Eventually, one server tells her that because of the reservations for the evening, they will need the table at 7:30, and as a result, the last time to put in an order will be 7:00. The diner replies that if her friends have not arrived by 7:30 (not 7:00), she will leave without ordering, and that she does not intend to order anything unless her friends arrive. The servers stop coming to her table.
The restaurant is heavily booked, and although there are numerous empty tables at the time, they are likely meant for reservations. In the meantime, a couple parties of 3 or 4, also without reservations, are waiting for a table to open.
What are your opinions on
 the diner holding the table with potentially no order
 the servers repeatedly asking the diner to order ?
My husband and I witnessed this recently (it was impossible not to), and we had completely opposite takes on this.
