At my shop, we pride ourselves on the experience we provide. A large part of that experience is customer interaction. Customer interaction is something that is only noticed when it is really good or really bad. I believe this is a large part of what sets businesses apart. Every single customer interaction is the most important one. What I tell my team is that no matter how bad a mood you are in, if everything is not going your way, or you have a line of cars two miles long, your number one priority is providing the most exceptional interaction for that customer. Go above and beyond. Be genuine and aware of the customers needs, letting them know that you care. I experienced first hand why every single customer interaction is so important last weekend. We are closed on Sundays, but I happened to be at the shop working on some stuff. A car rolled up looking at the menu and hoping we were open. Although I had had a long week of making drinks, I stuck to my guns of believing that every single customer interaction is the most important one. I was extremely outgoing and helpful to these customers and made them some drinks and got them some cookies. They were extremely grateful and happy towards my customer service and they went on to Yelp and left us an outstanding review. In conclusion, no matter what the situation or how you are feeling, be sure to remember that your interaction with that particular customer is the most important one of all.
