Ives and Jiménez detail the different companies offering free things for those who get their Covid-19 vaccines, including Krispy Kreme, which is offering a free glazed doughnut every day this year to those who provide proof of vaccination, and the Market Garden Brewery, which is offering 10-cent beers to the first 2021 people who present a Covid-19 vaccine certificate.
