Can’t Wait a Minute, Can You?
Do you know how much work drive-thru employees have to do? They don’t just take your order, but they also have to check with the kitchen or bar staff to see what’s ready and what isn’t. Then they have to deal with the car ahead of you when they pay. And you know how many payment systems there are now, right?
So, if the drive-thru employee asks you to wait a moment, sit back, relax, and wait for exactly one moment to pass. If you begin rattling off your order, the OP is going to wait until you’re done and pretend that they’ve only just heard you speak.
