Use 3 groups with one coordinator per group. 00:00–00:10: welcome and explain the activity. 00:10–00:20: distribute 30 tool tags to each group. 00:20–01:05: run the main activity. 01:05–01:20: collect feedback and reusable equipment. 01:20–01:30: clean the community hall and check the inventory.

Count the 90 tool tags before visitors arrive. Confirm a clear entrance and an accessible work area at the community hall, then give each of the 3 group leads the same timing sheet.

Supplies: 90 × $5.75 = $517.50. Reserve: $517.50 × 0.10 = $51.75. Planned total: $569.25. This is a planning calculation using the supplied prices.

Remove 30 units, leaving 60. Supplies become $345.00; a 10% reserve adds $34.50, for a total of $379.50.

Join Repair Cafe this Sunday at the community hall. Meet neighbors, learn together, and take part at your own pace. We will share the available tool tags across small groups. Supplies are limited, so please check with the welcome desk when you arrive.

Repair Cafe Sunday · community hall Welcome! Ask the desk about available tool tags and today’s small-group activities.

```python import csv def read_inventory(path): rows = [] with open(path, newline="", encoding="utf-8") as handle: reader = csv.DictReader(handle) if reader.fieldnames != ["item", "quantity"]: raise ValueError("Expected item,quantity columns") for line, row in enumerate(reader, 2): name = row["item"].strip() quantity = row["quantity"].strip() if not name or not quantity.isascii() or not quantity.isdecimal(): raise ValueError(f"Invalid inventory row {line}") rows.append((name, int(quantity))) return rows # Example row: tool tags,90 ```

The row `tool tags,90` should pass. The row `tool tags,-1` should raise a ValueError because a negative quantity is outside the stated inventory contract. An empty item should also fail.

Handover — Repair Cafe Location: community hall; day: Sunday. Inventory: 90 tool tags, allocated as 3 groups × 30. Before opening: count supplies, set the welcome desk, and confirm group leads. During the event: record shortages and visitor questions. After closing: count returns and write one improvement for the next meeting.

Ask: “Were 30 tool tags per group enough for the activity, and which step created the longest wait?” Record the answer beside the returned inventory count.

You are welcome to check in at the desk when you arrive. A coordinator can explain the current activity and see whether a group has space and spare tool tags. If the activity is already full, we can help you observe or find the next joining point.

Avoid guaranteeing a place or a set of tool tags before checking the group capacity. Keep the reply specific to the community hall session and offer a clear next step: speak with the welcome desk.
