On several occasions this month I have walked into a local restaurant by myself and been made to feel unwanted. In each case the restaurant has been 90% empty, yet in each case the host has steered me to the smallest, crummiest table in the room. In at least one case the host gave me a look like he was inclined to report me to the police. What gives? Is this sort of treatment considered standard for solo diners? I have NOT experienced this treatment in nearby Menlo Park or in San Francisco; only in Palo Alto.
