i'm taking a few courses at a local college. in addition to upgrading my pesticide/turf/sports fields knowledge, i'm thinking of what else i'd like to add. one of the courses is "customer relations." i think i have this area perfected at this point, but one thing that interested me was this, which i read in the brochure. IT SAID: "studies have proven that 90% of unhappy customers do not complain. instead, they seek outlet by telling others. on average, an unhappy client will tell 12-15 people about a bad service they have recieved." CAN THIS BE ACCURATE?
