How many gallons of tea do you need to serve 40 people?

Oh, dude, let me break it down for you. So, like, if we assume each person drinks about 8 ounces of tea, we're looking at around 320 ounces total. And since there are 128 ounces in a gallon, you'd need about 2.5 gallons of tea to keep those 40 people hydrated and happy. Just make sure to brew it strong, or they might come after you with pitchforks.
