Plan a Halloween Weekend Retail Staffing and Opening Hours Schedule for a Small Shop

You are a retail operations planner who builds realistic weekend schedules for small shops during busy seasonal peaks. Halloween weekend is coming, and I need a staffing and opening hours plan that matches my real headcount, labor budget, and expected foot traffic. Use only the details I give you. Do not invent sales forecasts, wage rates I did not share, or labor law rules for my region. If something is missing, mark it [NEEDS INPUT] and list it as a question.

Shop name, location type (mall, street front, market stall), and what we sell: [SHOP]
Normal weekday and weekend opening hours: [NORMAL HOURS]
Halloween weekend dates I need covered and any special hours I am considering (early open, late close, closed for a local event): [HALLOWEEN HOURS]
Staff list with roles (manager, cashier, floor, stock) and the hours each person can work that weekend: [STAFF]
Hourly or shift cost I am allowed to spend, if I know it: [LABOR BUDGET]
Busy windows I expect (trick or treat evening, Saturday midday, Sunday afternoon) based on past years or local events I know: [BUSY WINDOWS]
Breaks, minimum coverage rules, and any person who cannot work alone: [COVERAGE RULES]
Tasks beyond selling that still need time (restock candy displays, costume area tidy, closing cash count): [EXTRA TASKS]

Requirements:
1. Propose a Halloween weekend opening hours grid day by day. If I suggested special hours in [HALLOWEEN HOURS], keep them unless [STAFF] clearly cannot cover them, in which case explain the gap and offer a safer alternative.
2. Build a shift schedule table with day, shift start and end, role, and assigned person from [STAFF] only. Do not invent staff names or overtime availability I did not list.
3. Make sure [COVERAGE RULES] are respected: never leave a shift below minimum coverage or with someone who cannot work alone.
4. Block time for [EXTRA TASKS] before open or after close so the floor is not empty during [BUSY WINDOWS].
5. If [LABOR BUDGET] is provided, estimate total scheduled hours and flag if the plan looks over budget. Show the simple math. If no budget is given, mark labor cost [NEEDS INPUT].
6. Add a short contingency plan for a no show, a rush, or running out of a top Halloween item, using only roles I already have.
7. Write a one paragraph staff announcement that shares hours, who is on which shift, break expectations, and how to swap shifts.
8. Remind me to confirm local labor rules, minor work restrictions if any teens are on staff, and any mall or landlord hour requirements before publishing the schedule.

Deliverables:
1. Day by day hours grid
2. Full shift schedule table
3. Extra task time blocks
4. Labor hours check against budget if available
5. Staff announcement, contingency notes, and [NEEDS INPUT] questions
