Customer Service tips from my trip to San Fran

While in San Francisco I experienced some unique customer service. There is a genuine passion for customer service in retail and hospitality in the USA and I was impressed. 
Not once did I feel waiters, or staff were going through the motions of their job. They way people speak is very genuine, personable and open making you feel warm, welcome and comfortable. 

Here's my findings and a few thoughts you might be able to take away to your business.
