Train delays. Though the reasons for said delays can be pretty funny. These are some I’ve heard on my commute into London:
“Sorry for the delay to this service, we can’t find the driver.”
“This train will be slow running due to the number of passengers on board”
And my favourite, “We’ll be stuck here for a while while a farmer tries to get his cow off the line.” That’s what happens when you pretty much live in the countryside.
Not to mention the weather excuses. “It’s too hot,” “It’s too cold,” “There is a leaf on the line.” Plus the “trespasser on the line” line – that seems to happen on a weekly basis.
