At least once a day, if not twice, my husband and I go through the drive through at our favorite McDonald's.   Valerie is the voice we most often hear and who so cheerfully greets us.    Then we drive to her window to make our payment or receive our receipt for ordering through the App.   I don't know how she does her job!   She's literally managing two things at once:  taking the order or accepting payment for the order.   And she is unfailingly pleasant when she sees us and greets us like an old friend.   She's a wonderful ambassador for McDonald's and such an asset for your company.
