I like to perform random acts of anonymous vindictiveness from time to time. My way of 'Getting Back' at my local community at large.
My current favourite thing to do is to 'hide' winning scratchcards around town and let people find them. I make sure they are a decent enough win, of £5, £10, £20 etc and even mark up the winning combination with black marker pen. This ensures that anyone who glances at the card, at least takes a second look and doesn't just think its a card that wasn't a winner and someone threw it away...
What they don't realise though, is I sabotage the claim number thats needed to be able to cash it in ! I simply make it unreadable! That way, although its a genuine winning card, theres no way that the computer can validate it and pay it out!
Sometimes I wait and see who finds them, and sometimes I just walk away and never know. Gives me a warm feeling I guess
What random acts of anonymous vindictiveness do you like to perform?
