The only country that always surprises me for its agility and capability of improving systems and bringing new concepts is the US. The concept basically is to keep improving customer service to a point that others can’t but follow elsewhere in the world.
Simple, but very important for travelers – the hotels do not anymore require check-out, once you have checked-in with your credit card signed in. They drop the invoice in your room from under the door early in the morning, which you can check, leave the keys in the room and simply walk out of the hotel. If any charges are incurred after the invoice has been given, they can charge it to your credit card. The objective is simple, make the process so smooth that their manpower costs can be cut, while saving time for the customer.
Another thing I found that the smallest of transactions can be done in the US using credit card. Elsewhere, thye would want a minimum amount for a credit card transaction and invariably it takes longer than with cash. Not in US. So much so, that if a transaction is below a certain threshold, for example $10, they don’t even ask you to sign. The mantra is speed.
The Speed of Trust.
