Repeat customers, certainly, there's only so many of them you can have. I'm talking about small shops with 5-10 people heading out to service calls, and a lot of these is "throwaway" customers that need a water faucet changed or whatnot. At least here in Germany, in most rental contracts the responsibilities are split between landlord and renter, with the landlord being responsible for the heating, the water mains and the large fusebox, but the renter has to deal with everything under the scope of "Kleinreparatur". Exchanging faucets and siphons, wall sockets, installing laundry machines and other appliances, installing lamps, that kind of stuff many people (like me) can DIY but other people (like a lot of my friends) can't or don't want to, and they call in the professionals for an hour or two. And these guys have like 4-6 service calls a day.
