(WTNH) – At fast-food drive-thru, there is some proper etiquette to follow to make a smoother experience for all the cars in line.

Certified Etiquette Expert Karen Thomas says it starts with remembering that a drive-thru is for small orders.

Drive-Thru Etiquette

• A drive-thru is made for small orders with expediency in mind.
• Don’t Tailgate Car in Front of You – leave space
• Know your Order before arriving at the speaker, speak clearly
• Arrange payment method before arriving at window
• No add ons please once at the payment window!
• If a mistake is made, park and go inside to rectify – not at the window
