Which Level of Service Do You Provide? Let Them Know from "Hello"

One of the first things a greeting does is convey the level of service a customer may expect from your establishment. Are they going to get non-compliant service, compliant service, or anticipatory service?
Non-compliant service will push away customers every time. They asked for a glass of water and received nothing - except a grudging set of directions.
Compliant service is pretty much the baseline for the contemporary business world. It doesn't offend customers, but it won't win them over either. Complaint service can be well-executed, but it's not going to build loyalty for your brand.
Anticipatory service is extremely rare. But as we have discussed, this is where customer loyalty is created. When customers' wishes are anticipated, they get to bask in the magical feeling of being cared for. That feeling crates loyalty, which builds strategic value for your company.
SO, if you can tip your hand at the front door that this exceptional level of service is what they expect - if you can manage to literally "have them at hello" - you will predispose your customers to think well of you throughout the rest of the service experience
