That's not the point though. The point is that when you place a reservation, certain things are included. In the case of a restaurant, chairs are included. In the case of Delta, they explicitly state right under
the agreed upon price that there is a seat available that I can reserve. It might be close to the restroom, sure. But they should not list this offer as inclusive of seat selection if there are no seats to select.
For some reason you fail to acknowledge that features listed under the price must be included in the price.
> Try reserving a specific table at the restaurant. An hour before the dinner.
Restaurants don't allow you to go through the reservation process to only suddenly mention at the last stage that the table has no chairs, or no table top (just table legs).
