Please don’t yell at the driver/retail rep. He goes back to a warehouse that’s supplied by a bottler—all local employees. Who is he going to “report” your dissatisfaction to? His dispatcher? The guys who load his truck?
Retail delivery/merchandising isn’t easy work...having somebody chew you out, on a retail sales floor, will probably bring harm to the raises/bonus of the driver as the store management may incorrectly assume that the driver did/said something to offend HIS store’s customer.
Seriously...boycott away. Write or call the Kraft 800 lines and websites—but leave the lowly deliveryman alone!
No need to yell or start a fight, just inform. If enough people do that and sales drop word will trickle up. What are you, married to a delivery driver? If you are accept my sympathies in advance.
