I dine alone often and can only remember two good experiences. One was in Vail, CO and the waitress was so good, she made me feel like I was her only customer. She was so attentive that I was never aware I was alone. The other was a family style restaurant I went to every Friday night. I started by bringing a book, but when they realized I was going to be a regular, they saved me a regular table in the corner of the room where I got to watch everyone else during my meal. They even started moving me ahead of the line when it was crowded and called out my name when seating me. Both show you that the waitstaff make all the difference in the world. I have posted to other sites how waiters give poor service because even a good tip from a single diner is less than a bad tip from a table of 6. I have left as much as 100% tip for exemplary service.
