Sue Cleaver made a "few fake calls" to taxi firms to prepare for her role on \'Coronation Street\'.
The 56-year-old actress - who plays Eileen Grimshaw on the long-running soap - has revealed she went the extra mile ahead of her first appearance on the programme in 2000, when her character arrived as a switchboard operator with the taxi firm Street Cars.
She said: "I thought about taxi firms I used and how they answered the phone and the flat voice they used.
"I have to admit I made a few fake calls where I didn\'t need a taxi, just to talk to the operator.
"Then I\'d ring back and say: \'Oh, I\'m so sorry, I\'ve got to cancel that cab.\' I\'m amazed I\'m not blacklisted around Manchester\'s cab firms really."
Sue is celebrating two decades on the soap this year - even though she only initially thought she\'d be on the cobbles for 12 months.
The actress also revealed the affection she has for her on-screen character, describing Eileen as "down to earth, level-headed and loyal".
Sue - who previously starred in the BBC comedy series \'Dinnerladies\' - told the Sunday Mirror newspaper: "I originally said I\'d stay about a year, but the place is so seductive.
"Everybody knows an Eileen. She\'s every woman, she\'s down to earth, level-headed and loyal.
"She\'s a great friend, but cr*p at everything else."
