Danny lacks the intelligence to actually be able to lie in a convincing manner.
Assuming I believed he had a job, and was at work by 10am there is no way he got off the plane, through immigration, collected his baggage (especially at Manchester who are one of the slowest in the country), and got back to Leigh via the M56 and M6 in 9am traffic. Not a chance. Also how did he get back? Connor dropped them off so did Connor take the day off work to pick them up? Or does this magical 45 minutes include train or tram to centre of Manchester, then local train to Leigh or Atherton depending which is closer? Because that’s 1.5 hours of public transport alone.
Then if the flight was delayed, was he actually late for work? Or had he never been due to work that day because he was supposed to be on a later flight?
Lying about absolutely pointless tit like this means he 100% lies about bigger stuff. Though the fact that he maintains his name is Dalimore when it’s bleeping Bishop is probably the biggest indicator that this bleep would sell his Granny for 30 seconds of fame.
