If you notice that your customer is having difficulty accessing your goods, services or facilities, a good starting point is to ask “How can I help you?”
Often, there are simple solutions. For example,
You could offer to serve the customer at the door, at another more convenient location, by phone, or by delivery to their home. You might also consider low-cost solutions such as a portable ramp that can be set out at your shop entrance on request and if suitable to the situation.
Ask the customer in writing if using a pen and paper to communicate would be a good way to serve him. Remember, if you’re discussing confidential information, offer to return the notes to the customer or to destroy them.
Offer to bring the products to the customer.
Offer to read the menu out loud, or post the menu online so they can access it beforehand.
Offer her a place to wait her turn for service in an area apart from other customers.
Be prepared to help open the door.
Your customers are your best source for information about their needs. Being flexible and open to suggestions will help to create a good customer experience. A solution can be simple and the customer will likely appreciate your attention and consideration.
