I think this is great and I’m buying some Post-Its!
I keep doing the post-its in men’s rooms like on towel or soap dispenser because only place I can really do without being on camera now days, done a few on the soda machine at circle k or 7-11 when I can if nobody around... but also started putting one in the menu before I hand it back now too at a sit down restaurant... LOL. I usually have a pad in my pocket and if I see a good place I just do it... IF not a random customer seeing it, maybe the guy or girl that pulls it off and tosses it.
