When coming to a drive thru of any kind, especially those that rely on an external speaker system, shut off your vehicles air conditioner/ heater. The A/C more than the heating element requires and an additional part of your engine to run as well, thus creating more noise. The reason you as the vehicle operator can’t hear it is because there is about 3 feet worth of vehicle between you and it with a lot of noise baffling material.
Most of us on the other side of the drive thru have a hard enough time hearing anyone over the shitty speaker system to begin with. Let’s not add the extra noise.
Just to be clear, we are not allowed to ask you to shut off your radio, engine, etc… The corporate masters consider that to be bad customer service. This is one of those cases where we need you to help us so that we can help you.
