Does the menu on your website match the menu in your store?
Think beyond food. Does your website say you do tax work, when you also do financial planning? Are the phone number and address current? Are they at the bottom of every single page?
Is it easy to find you, and know what you do and don't sell when i walk in the door? The customer who has researched you is probably in a buying mood when they walk in. Don't disappoint them by no longer selling something they saw on the website.
You do have a website, don't you?
