Arriva North West - St Helens Depot

RE: Arriva North West - St Helens Depot
Would love to know how today on the 89 early afternoon 2ish before schools finish, one arrived at the Airport 13 minutes late (fair enough you and I may normally say). It then went straight back out so was now only 5 minutes late leaving the Airport - Again fair enough. However by the time we got to Huyton it was now 11 minutes late, and by the the time got to St Helens was 18 MINUTES LATE, the next 1 was virtually behind us arriving in St Helens!

At First i thought might have just been the timetable, but the next one was spot on, as were all the others I checked on the app at that time.
How on earth can one driver make himself basically an extra 13 minutes late in both directions?!?!? And why would he want too! 13 minutes too the airport, then left 5 late, arrived 18 late at St Hel, so another 13 lost on that journey. God knows how late he got by the end of his shift!!
