I always feel that Clint Eastwood movies have much to teach us on this subject:-

1) Clint is in pretty good shape. Nicely turned out - good choice of sports coat and jumper.
2) He has got several big guns.
3) Public officials like Clints bosses are nasty pieces of work - weak morals, lacking in moral fibre, really complete arseholes who are bothersome to Clint, whom they SHOULD get down on their kness and thank for always saving the day with his big guns, and perfect dress sense.
4) Ugly people are up no good. By and large greasy little bastards much given to rude behaviour. Clint can spot them a mile off, thank goodness.
5) We need a few more like Clint to sort out the the ugly customers.
6) Get a big gun, improve your dress sense, go to the gym and work out. Clint has given you a blueprint - something to aim for. Bullies won't mess you about then.
