Most of that stuff seems pretty reasonable.
When I had my cleaning business, we were always having to clean up after plumbers, painters, electricians, etc. (for our RE customers). Sometimes the apt. manager would complain, explaining that the resident had passed the cleaning inspections. I'd point out that it wasn't the resident who had cleaned their paint brushes in the bathtub, nor had they sanded the cabinets and filled the apt. w/ dust.
I never park in the driveway, even when they invite me to. I always clean up everything (a good way to ensure all your tools leave with you.). I haven't used any pads. Good idea, I'll have to look into that.
pad for call book? W?
The shoe coverings are top notch, but I'm not sure that they'd be worth the effort. I usually hit my truck a minimum of 3 times, and taking 'em off & putting 'em back on might be over the top. But I live in California. reasonable rain, & no snow.
I always hand out a business card and introduce myself. I also stand and introduce myself when another adult comes in, if reasonable (I ignore kids & teenagers - with the teenagers its mutual
The fridge magnet and service sticker is great advertising. I love that stuff. People will call you who bought a used appliance w/ your sticker.
The uniform is important. I prefer to wear a collar, and keep my shoes polished (or equivalent). I'm still looking into tweaking my uniform. I'm comfortable in polo shirts, but a button up Ben Davis type work shirt might be more professional. Navy Ben Davis or Docker type pants preferred over jeans.
Hygiene is important too. brushed teeth, hair, deodorant. A plumber in San Diego advertises based upon hygiene - he's the "smell-good" plumber.
Keep the customer informed about what is going on with his appliance, give him a safety tip or two, plus some useful info: defrosting, lint cleaning, HE detergent use, etc. Plus, if I ever have a conflict, I can give discounts off the next service all day long. Good perceived value, and if he calls back, I retain the customer.
Bring my own paper towels.
What do you guys think about accepting water, sodas, or lunch?
