Luckily, there are many different types of dining establishments. We run a casual space where servers are encouraged to be real, service oriented people who develop strong repore with their customers. Part of that may include sitting down at the table. Each customer, like each server is made to feel comfortable in varying ways. One aspect of the talented server, is being an intuitive person who knows when to sit down & hang out and knows when to be polite, informative and consise. Having one rule, for all customers, in all environments, is insane. Maybe I feel a little opinionated right this moment... Being both an owner and someone who serves, It annoys the hell out of me when customers have a condesending approach to the staff that serve them. If you are uncomfortable with warmer styles of communication, stick to fine dining environments or counter service where staff are more than arms length away. The casual approach we try to take, changes the role of a "server" to more of a location specific consultant that you the customer has hired for assistance with both menu and any other timely needs you may have during your stay. The more a customer feels at home with all their needs met the better the job we have done. That being said, I still value the concept of the customer is always (almost) right. This gets back to us all having different expectations and we should train our staff to look for the visual indicators on what type of experience the customer is looking for.
