Take magazines to a waiting room

Most likely the office manager will be pleased to be able to put out new reading material (which is old to you). You get to declutter, and the experience of waiting for a doctor or dentist gets marginally less horrible for those doing the waiting (even if, for some, one of the few pleasures of visiting a dentist, doctor, etc. is skimming through decades-old publications they'd be embarrassed to have in their own homes).


Effort involved: only as long as it takes to load up some magazines and find a waiting room. If you're reluctant to talk to people inside, you could always anonymously leave them outside.
