Sticking it to The Man

got the train to Preston last night for my mate Som's birthday celebration - on the way there I didnt get asked by the conductor to pay for a ticket, even though the passengers around me did. then with the return journey being around midnight, the guard didnt dare poke his head out of his compartment and so again wasnt asked to supply a fare. result!then this afternoon in tesco's I got handed the wrong change - which means I made three quid on the evil empire that is Tesco.how have YOU stuck it to The Man lately?
