One of the most common things I see in independent restaurants is that the servers never ask if I have been to the restaurant before. Should they?
Yes, for many reasons! First time guest are another opportunity for your restaurant to shine. Typically, first timers want to have a good time and a great meal. They chose your business to visit. Statistics also show they spend more. This also presents opportunities to engage them in your loyalty program or ask for a review. Chances are it will be a good review if your team is functioning well.
Make sure you have the server tell the manager there is a new guest. Touchdown no the tables is always important. Winning new customers is even better.
