7. The Credit Card Scam
This is a scam which most people might fall in. Whenever you get a call at your hotel room and someone from the front desk asks you to repeat your credit card number or give another card number telling you that there went something wrong with the card on file, it might be a scam which is willing to push you towards a great trouble. Hence, when this happens, go to the front desk by yourself to be sure and never provide the credit card number on the phone.
