I went to the movies yesterday…
So, the place is packed. Lines for the ticket counter is 25+ people deep. There are 6 ticket vending machines sitting there, happily waiting dispense tickets. Empty. No lines. No people. No usage.
I waited and watched for about 15 minutes. 3 people used the machines. Nobody came to the slow moving line and suggested they use a machine. People were in line complaining about how slow the line was moving. People were using credit/debit cards in the line so no excuse there.
As you think you will change people’s habits with your stuff; go the movies.
