Those who spend the least and ask for the most before ordering will do the same after the sale. Cutting them out is both a good lifestyle decision and a good financial decision. Low-profit and high-maintenance customers like to call operators and spend up to 30 minutes on the phone asking questions that are unimportant or answered online, costing—in my case—$24.90 (30 × $0.83) per 30-minute incident, eliminating the minuscule profit they contribute in the first place.
