Yeah I can't say we ever got anyone who used "clown" as a job reference

I could see a business like that using a mascot of some kind.
Dog walking seems like a very novel business idea, and if it has paid the bills for while you have a genuine good thing. As a person who only visits cities I wasn't familiar with the concept until I actually read that this is what you do. I can see where there could be some misunderstanding from a bumpkin who doesn't get out much. Maybe someone visiting the area. The people who live there though should know better I would think.
Just recently I heard about another business that hangs your Christmas decorations for you. This is yet another one of those things that I never knew existed. I guess if you make big bucks doing something you can't be bothered to walk a dog or hang Christmas lights. More power to you in finding that niche.
