 Focus on a communication strategy out the gate so everything is extremely clear on what behavior is tolerated and what is not tolerated. The first thing you should do is communicate effectively about your policies in your business. That means extremely clear to the point and consistent newsletters or even text messages to customers, signage if you have a retail location, particularly if there's a mask policy. Communicate that extremely clearly so there's no question that the customer must put on the mask before they come into your business. Make it easy for them. Maybe you actually have free masks for people when they come into your doors or you've set up an almost a pop-up shop outside of your retail location to keep people safe and social distance. Support your employees because we've seen a lot of employees actually catch some heat for simply enforcing the policies of the company and you're seeing these stories go viral on social media again and again of customers who don't want to wear masks and are getting aggressive and angry about it. You can protect your employees by enforcing that communication policy. Just making sure everything is extremely clear that you even provide masks to customers and when things go wrong you support the employee rather than angry customers who are behaving badly. If your customers are trying to drag you into the gutter by causing fights, by not wearing masks and not obeying the policies of your business, it is 100% okay to not serve them anymore. None of us enjoy confrontation but it is important that you protect your good customers and your employees by keeping everyone safe and being very stern on what behavior you will tolerate and what you won't tolerate. I know these are unpleasant emotions right now but if you simply take a deep breath, go for a walk outside, listen to some music, calm down, it'll be good for your teams and for your customers if you're dealing with these difficult situations but you're mentally in a calm place.
