My friend and I had a room booked at the Mandarin Oriental. I arrived at midnight after a 25 flight from the other side of the world. The hotel was booked with my friends credit card who was arriving a day later.
The hotel had been sent my name and check-in details by my friend in advance.
I provided my passport but when I couldn't produce my friends credit card, they turned me away.
The check-in staff Sebastian was one of the rudest and obnoxious people I have ever met in a luxury hotel.
I nearly ended up sleeping on the street. By the grace of God another guest at the hotel saw what was going on. This Good Samaritan paid for a room using his credit card until the next day when my friend arrived.
