Starbucks sells convenience. You must sell experience. What does your shop feel like? Smells like? Sounds like? These sensory details are what build memories.
Curate your playlist. Do not just put on "Pop Top 40". If you are a cozy reading spot, think Jazz or Lo-Fi. If you are a bustling downtown espresso bar, maybe energetic Indie.
Train staff to greet every person within 5 seconds of entering. "I'll be right with you" is enough to acknowledge their presence and make them feel welcome. Eye contact is powerful.
