I use my credit card a lot for all sorts of things. In the past 3 years I can only remember my card being rejected once. An when this happened I immediately got an automated call that allowed me to confirm my transaction (so I was still able to use that card to pay).
My card was also stolen once (someone copied the magnetic stripe). Once this someone did a transaction on the other side of the country I immediatelly got a call from Amex which proceed to refund that transaction and to send me a new card. IIRC a replacement card arrived in the mail on the next day. In the mean time I just used my debit card to pay for things.
