Q. What is the etiquette around tipping service people, such as a plumber? – Unsure About Tips

Dear Unsure: Offering an additional bit of cash as a thank-you for good work is hardly ever inappropriate. If a service or repair person employed by a company (Acme Plumbing & Heating, say, as opposed to Joe the Self-Employed Plumber) provides service you feel is especially good, ask if s/he is allowed to accept tips. It is not necessary to make the amount a percentage of the total, but start with a $10 bill and go from there. (Yes, cash, not check.) If you have a self-employed handy-person or other helper who comes regularly to your aid, you might consider an annual holiday gratuity or a gift card.
