I did a mulch job for a lady last week which I estimated would take about 10 or 11 yards. Her estimate was for 11 yards. The supplier I use often times brings more than I order and in some cases as much as 3 yards more. Case in had, I did a mulch job 2 weeks ago, orderd 7, and he delivered 10. Of course I only was charge for the 7. Any how, this ladys was going to use about 10 or so, so I ordered 8 from the supplier figureing he'e bring me extra as usual. Sure enough, he brought about 10 or so. which was enough to do the job. I actaully had a little left over. I billed the customer for the original 11 yards as estimated. Now shes bitching because she called the supplier and asked them how much mulch I ordered, and they told her 8. So now she ensists on paying only for eight yards. Even though I only ordered 8, I know I laid about 10 or so. DId a really good job, cleaned up well. But she will only pay me for the eight I ordered. I explained the situation to her and told her the best I could do was charge her for 8yd of material, but I was going to charge her for 10yd of labor. She's pissed.
