I just always assume that soaps exist in their own alternative dimension, where time doesn't matter!

So is tonight's Friday double bill doing to be Friday or Monday, ie is Pat doing one tonight?

I feel really sorry for the Corrie editors at the moment. You can tell they've had to mess about hugely with timings because episodes are finishing and starting at weird moments. Two or three days passed and Sarah was still arguing with Gary on the doorstep!

They meant next Thursday, because Vinny and Phelan are planning to scarper with the money on Monday.

Their schedule was thrown into chaos because of ITV's decision to show a football match (!) last Friday. They lost two half-hour slots as a result, so the episode shown tonight was probably scheduled for Monday (episode 2) or yesterday (Wednesday), hence the foul-up over which day of the week it is in Weatherfield.
