Sean McElroy lined up at 11:15 p.m. Tuesday so he could be the first customer to walk through Krispy Kreme’s doors in downtown Denver on Wednesday morning and leave with a free dozen doughnuts for this week and every following week for a year. Nearly 200 people waited on 16th Street Mall, some since the night before like McElroy and others straggling in between 4 a.m. and 6 a.m., in the hopes of getting free doughnuts.
