Pastry Dispatch

Serve five customers before two walk out. One starts waiting; another arrives every five drops until six have arrived. Tap a customer, select its exact pastry tier, and Serve. Orders never silently overwrite each other. Each successful drop spends one patience for every waiting customer. Serving, reserving, selection and blocked attempts spend no patience.

Choose a column to drop the next pastry. Equal orthogonal neighbours merge into a higher tier at the new pastry, trying left, right, up, down, then repeat. The bag falls after that merge chain. The forecast shows the resulting selected column and warns of walkouts.

Reserve one selected pastry on the display to protect it from over-merging and free space. Only an exact customer can take that display pastry; it cannot return to the bag. This can save a future order, or clog the display if you prepare too far ahead. There are 30 dough drops. Ready orders may still be served after the last drop. Retry repeats this fixed shift.
