Communication with your customers is critical! They must feel confident that you are providing outstanding service while at the same time implementing actions to protect them. Remember, perception is the key. You can be doing everything right; however, if they perceive that you are ignoring the issue — or the opposite, going overboard — they may not return.
As customers enter your retail space, they should see signage and/or a greeter who can explain and assist them with the different actions you have taken.
