The rule of thumb here is 2 tablespoons of coffee beans (or 2 rounded tablespoons of ground coffee) per 12 oz. cup, plus 3ish extra tablespoons for the pot. So if you were making coffee for six, it'd be 12 + 3½ = 15½.
If you're using whole beans:
Put your coffee beans into your grinder. If your breakfast guest doesn't like the sound of the coffee grinder, either grind it the night before she comes over, or tell her to cover her ears before grinding. Grind the coffee, shaking the grinder to be sure and get all the beans. Do this for about 10 to 15 seconds or so, until you don't hear any larger chunks of bean rattling around. You don't need a fine espresso powder, but you don't want it to be not fully grounded. Remove the top from the grinder, and tap your coffee into your coffee pot's filter.
If you're not:
Put your coffee into into your coffee pot's filter.
Pour the water into the coffee pot's resevoir. Turn on your coffee pot. Finish making breakfast. Bring it to your breakfast guest.
