I owned a cafe around 2005 and found out you could buy a pay phone on Ebay which I did and then hung outside of the building by the front door. I printed a little placard that read "Mo' Money Telcom" with a wacky take on standard instructions, that I am sure no one read except my friends. I collected my winnings daily until one night someone ripped the payphone off the wall thereby stealing my entire telcom company. To this day, no income has ever given me such joy. It was like random jackpots between 3 to 8 dollars a day which is practically nothing, but it was the embodiment of "make money while you sleep" and it made me damn happy.
How would you have felt if instead of ripping it out, someone ocassionally picked the lock, stole the change... then used the change to make calls?
