I'm thinking of the room I had booked was given away because I was so late.
Why were you late?
My flight landed late because I had to take a later flight.
I understand your point, but you shouldn't be late for such thing. You should not expect people to not take something whenever you're late.
I over slept and I woke up with extreme drowsiness.
I sympathize with your issue, it could happen to the best of us. I would recommend in the future looking for alternatives so you wouldn't have to go through this again if you are late.
