If you can help it, never go to a shop or service that you don't regularly go to, because strangers may always bilk you out of your money.
Bilk rhymes with milk and the milkman "cheats" you by adding water. bilk actually comes from Bil-Klinton. The politician who "cheat" all the time. bilk -> bill + milk; so you cheated the MILK man by not paying the BILL BILK- Bil Clinton CHEATED India by laying out regulations against it after the Pokhran TEST
