You are offered assistance but not stalked. If you have an issue, it's handled promptly and courteously. Bad customer service-lowes, I'm buying everything for a bath remodel after we have gutted it down to joists and studs. After noticing the drywall i need is stacked 2 pallets over my head i ask for help, Lowe's guy impatiently asks if I have a list. I tell him the large items I need, he says he will collect it all whole I pick up the smaller stuff. 45 minutes later I come back to find 5 sheets of cement board and that's it. The guy is also gone. Good customer service, I walked into a different lowes 2 years ago for. The same purpose (gutted a room). The gentleman in lumber not only helped me find and load the lumber but he followed me to electrical, plumbing, bath cabinetry, etc, answered all my questions or found someone who could. Brought every bit of it to check out, waited while I checked out and then loaded my truck for me.
Good customer service involves meeting a customer's needs and going out of your way to make sure that the customer gets to enjoy his or her shopping experience. The simple act of a shopping attendant saying hello is in itself good customer service.
I spent several years as a supervisor for customer service representatives. The first point I believe, is to be approachable and LISTEN. Repeat back to your customer a few points they said, so they'll know you were listening. Don't be afraid to let them know you need to ask for help on the issue. Say "Thank you" and "I'm sorry" in earnest. Follow-up on the problem. If possible, make helpful suggestions. Be honest. Do what you say you're going to do and don't leave the matter unresolved. If you can, call them back with a resolution.
