Today's waitstaff isn't told that they are in or trained in the "hospitality" business. It's get the order, get them fed, and get them out for the next customer. Everything is go-go go and rush-rush rush these days, and it's miserable for everyone.
He that would make his own liberty secure, must guard even his enemy from oppression; for if he violates this duty, he establishes a precedent that will reach to himself.
Thomas Paine
