Hi Christoph, as always very interesting and informative post. Just one small thought from me - a total novice - I found the wording around the no-coffee days a little bit confusing. "π, the probability of getting a zero coffee day" implied to me that (1-π) had to be a coffee day (I recognise now it's just a way of illustrating the Poisson zero count possibility.) Maybe a better way of describing would be π is the probability of making an explicit decision not to have a coffee on a given day while λ is the number of coffees per day when one hasn't made that decision e.g. can also have 0 coffees due to forgetting or being too busy rather than because you explicitly *don't want one*.

Again not intended as criticism but maybe this note helpful for anyone else who's briefly stuck on that! Thanks again!
