A coffee chain in Amsterdam is trying something unique to advertise their brand across campuses. They are giving away free coffee coupons to college students who agree to sneak in a branded slide from the coffee company into their PowerPoint presentations.
These advertising slides resemble coffee-stained paper napkins and some of them carry pretty funny captions like "I got free coffee to put this slide into the presentation" or "Drink Coffee. Copy from Wikipedia".
To claim the coffee coupons, the students are required to post a picture or video of the classroom where that presentation was made. Here’s one such video capture.
