Does anyone have ideas for dealing with volume on mic verses volume to hear others? We have a drive thru that is on a hill, and my voice apparently echoes loud to the customer. However, it can be challenging to hear the customer if I turn my volume down, and they are distracted, mouth turned away from screen, mumbling etc. Could I place something on my mic to muffle or lower my volume, yet still hear others? Plus it gets loud inside the store. thanks.
