this fight, and it's still a real struggle. >> so then do most restaurateurs welcome this, then, that patrons will have to show proof of vaccination? >> i think at the end of the day the requirement of vaccination cards is something we can both handle and support. and we welcome anything that will keep our guests and our team members safe. but it is problematic for restaurants in some ways. it does cause us extra labor. people can be arguementative at the front door. and in chicago you don't want to give people extra reasons not to dine when it's 5 degrees outside. but at the end of the day, we're happy to do our part. the variant spread that is the problem cost multiple staff members work in december.
