When I was single and working at a restaurant, I met some of the nicest people you could ever imagine. Yes, I did also meet my share of jerks, but people who regularly came in to see you made up for the meanies! Hell, the restaurant is where I met my current boyfriend of 3 years! Of course we worked together, so I guess that makes my answer work. Sometimes it is hard to work with you significant other, but it sometimes works well for others like me!
(We don't work together anymore since we've both graduated college and began our "real world" lives!)
