No. No. No. No.
I agree with almost all of this article, but I’ve seen this type of line in many similar articles, and I vehemently disagree. PMs don’t do beer runs, coffee runs, donut runs, burger runs, pizza runs or any other food/beverage runs “for the team” UNLESS EVERY OTHER MEMBER of the team will do the same when appropriate.
A good PM would have some foresight and plan for the beer/pizza/donuts etc. to be delivered or brought in advance, because a good PM realizes that their time is very valuable and beer runs are not a good use of their time.
