I discovered recently this sort of things works amazingly. At my company it used to be that it would be impossible to hold a punctual meetings (theres was always at least 1 person who would arrive 10+ minutes late). We made a rule, if you arrive late you invite everyone to donuts. It didn't work. Then we made it donuts + coffee. Boom it worked flawlessly. Every single meeting now starts on time. People make a huge effort never to arrive late and it's had a great impact on productivity.
