PROBLEM TO BE SOLVED: To prevent a pseudo suggestion presentation from becoming monotonous.SOLUTION: When a display mode of a reservation display changes, a suggestion presentation (e.g., a reservation change suggestion presentation) for suggesting a change in the display mode of the reservation display can be performed, and when a display mode of a reservation display does not change, a pseudo suggestion presentation (e.g., a pseudo reservation change suggestion presentation) in a mode same as the suggestion presentation can be performed. Also, a change pattern of the display mode of the reservation display (e.g., a final display mode of the reservation display) is determined, and according to the determined change pattern, a performance frequency of the pseudo suggestion presentation is determined among a plurality of performance frequencies (e.g., to be determined from any one among: at a different probability according to the final display mode; without a pseudo reservation change suggestion presentation; and frequency of appearance (low) to frequency of appearance (high)). When a change pattern in a kind with a high reliability is determined, as a performance frequency of the pseudo suggestion presentation, a high performance frequency is likely to be determined.SELECTED DRAWING: Figure 40 |
