Then they watched as visitors came in droves to spend the holiday week and decided to close until they feel safe about reopening. âI agonized over it,â said Melanie Hathaway, co-owner of Dover Bar and Grill. âI was like, is this the right thing? We were all stocked up, had our staff ready. We were nervously excited about Christmas week but ready to go. It just felt like it was getting overbearing.â
