Is your mail man/woman late?
Royal Mail (in the UK) don't guarantee a delivery time unless you use its "Next Day Delivery Service", in which case the item would be delivered by 12 noon. Our mail has been known to arrive between the hours of 7am - 5pm.

Do you ever see them?
Only when I'm taking the day off work.

What are your feelings about mail people and the fact that they get tons of time off because they work for the government?
In the UK, Postmen/Postwomen certainly don't get "tons of time off".
