Block Tables vs. Non-Block Tables

When managing table reservations, there are two different approaches: blocking tables and not blocking tables. Each method has its advantages and potential drawbacks depending on the desired balance between efficiency and user experience.

1. Understanding Block and Non-Block Systems

Block Tables

Blocking a table means that when a user selects a time and table for a reservation, that table is temporarily held so that no other user can book it until the reservation process is completed or abandoned. If the user does not complete the reservation, the table is released back into the pool of available tables.

Example:

  • User A selects a table at 7:00 PM → The table is blocked immediately.
  • If User A completes the reservation, the table is confirmed.
  • If User A does not complete the reservation, the table becomes available again.

Non-Block Tables

A non-block system does not hold tables when a user starts a reservation process. Instead, a table is assigned only when the user confirms the booking. If multiple users are in the process of booking, the first to confirm gets the best available table.

Example:

  • User A selects 7:00 PM but does not confirm yet.
  • User B also selects 7:00 PM and completes the reservation first.
  • The system assigns the best available table to User B.
  • When User A tries to confirm, the system checks again for available tables.

2. Configuration Differences

In block mode, the system ensures that tables are temporarily held as soon as a user starts the reservation process.

In non-block mode, tables remain available until a reservation is confirmed.

3. User Experience

When users start making a reservation, the UI and form header may look slightly different based on the approach used:

  • Block Mode: Users see a message indicating that a table is held for them.
  • Non-Block Mode: The system simply checks availability before letting users proceed.

4. Pros and Cons

Blocking Tables

✅ Ensures fairness, preventing overbooking.

✅ Guarantees a table for the user who starts a reservation.

❌ Can lead to inefficient table use if users do not complete bookings.

❌ May create unnecessary bottlenecks when high demand causes multiple blocks.

Non-Blocking Tables

✅ Maximizes table efficiency by ensuring only confirmed reservations hold tables.

✅ Reduces the need for automated unblocking systems.

❌ Users might lose their selected table if someone confirms before them.

❌ Can cause frustration if users take too long to complete the reservation and lose their spot.

5. Which One Should You Choose?

  • If you prioritize fairness and ensuring users get the table they initially selected, choose block mode.
  • If you prioritize efficiency and reducing unused blocks, choose non-block mode.
  • For high-demand situations where multiple people book at once, non-block mode may work better to optimize table turnover.

Both approaches have merits depending on your business needs. Consider user behavior and restaurant operation flow when selecting the best option for your system.
