I like having company when I eat, but it doesn't bother me to eat alone - in private or at a restaurant. I work third shift and I am alone for most of that shift, so I always eat alone at work. The last time I traveled for work, I ordered room service quite a bit and ate many meals in my hotel room because when I ate in the restaurant, it was hard to get the wait staff to notice me (so I could get refills on drinks, get my check, etc.). They were usually busy with larger parties and the service for me by myself suffered. When I had my meals delivered, the service was always great!
