No, we don't waste their time or make them late, just give them decaf. >D

Actually, I've only done this once and ended up feeling terrible afterwards. My husband (who has three BA's and is working on his MPA), however, got tired of one Suit treating him like some imbecilic dropout lowlife, so for several months straight made his four-shot skim latte with decaf, then suddenly put him on regular caffeine again.
