We have a Bunn coffee machine - 2 pots. We keep a pot of hot water at all times. The other pot is set up to run at a moments notice. The hot water is used for tea - (many kinds), hot chocolate and hot cider which we have in packages. Price for these - $1.00. We offer free refills on the tea only (water
).
When we started out we did free refills on the coffee since we had the pot made and it would go to waste. But after a while we added an extra large cup (16 oz - $1.50)and did away with the free refill. (No complaints - I am not sure anyone noticed). You will never make a significant profit with the coffee but you try to make people happy and cover your costs.
Demand for coffee is not significant and you don't want to make a pot ahead or you will end up pouring out a lot of coffee. We spend the extra money for coffee in the filter packs so we don't have to worry about grounds in the cup. We practice the art of filing the cup directly from the spout rather than waiting for the entire pot to fill so it doesn't take too long.
Now I don't particularly want to make coffee because I have a cappuccino machine and I prefer to sell cappuccino (and pay for the machine).
