My business is mostly residential, as I've said before. I do support some small businesses (an accountant, Civil Engineering works, a Subway franchisee, Hairdresser, an Auto Electrician and a few others) but much prefer to do residential. As
@nlinecomputers computers so eloquently stated (lol) "teaching Grandma to Facebook" is exactly what I like doing! Yes, it can be frustrating, yes, I feel like running from the house screaming sometimes, but it's a great feeling when you show an older person how easy it is to use Skype to keep in contact with that Son in America, or that Daughter in England etc. Email, websurfing, Facebook etc opens up a whole new world for older people! (And they make great biscuits!)
90% of my residential clients never question my prices, they just pay what is owed.
I like that!
