Drive-through no-nos

Drive-throughs (aka drive-thrus) are the ultimate in dining convenience, but make sure your habits keep it that way for everybody else.
Not knowing your order

Think of the drive-through as the express lane of the restaurant. Don’t know what you want? Need some time to decide? That’s totally fine – just go inside so you can take your time, ask questions and so on without slowing down the express lane.
Some restaurants even measure the time it takes their staff to process each car’s order, so slower cars can actually affect a worker’s performance rating.
Here are 10 polite habits that restaurant staffers secretly dislike.
Making it hard to hear your order

Your turn to order? Pull up and talk clearly into the speaker. Don’t mumble or face the back seat while ordering. Likewise, don’t yell or shout into the speaker. That’s just bad manners.
One of the top pet peeves of drive-through workers? Having everyone in the car say their own order, especially your kids. It’s hard to hear, which slows things down and increases the likelihood of a mistake in your order.
