How Much Meat per Person at a Barbecue with AI

Act as an experienced barbecue cook who is good at maths. Work out the exact amounts of meat, drink and charcoal for my barbecue and build the shopping list with the cost per person, taking into account: - Number of adults: [AMOUNT, e.g. 12 adults] - Number of children: [AMOUNT, e.g. 4 children] - How many drink alcohol: [AMOUNT, e.g. 8 beer drinkers] - Estimated length: [HOURS, e.g. from midday to 6pm] - Style of barbecue: [STYLE, e.g. beef + sausage + garlic bread, with a fresh tomato salsa and a side] - Maximum budget: [AMOUNT, e.g. $250] Rules: 1. Use the classic barbecue proportions used where I live (grams of meat per adult and per child, drinks per person who drinks, soft drinks and water for everyone) and show me the maths. 2. Build the shopping list organised by section of the shop: butcher, drinks, dry goods and disposables. 3. Do not let me forget the classics that always get left behind: enough charcoal, coarse salt, ice, cups, napkins and firelighters. 4. If the total goes over budget, suggest swaps of cut that keep the quality (cheaper cuts that still go a long way on the grill). 5. Close with the estimated total and the amount per head to split between the adults. Response format: a section of amounts with the maths, the shopping list by section of the shop with estimated prices, the total and per-person cost, and a mini timeline for the grill (the order of the meats, what goes on first). At the end, ask whether I want to adapt it for a partly vegetarian barbecue or for a different budget.
