A free cup of coffee could be just what the doctor ordered. On Friday, Dec. 18, anyone can purchase a cup of coffee for health care workers in Little Falls when Adventure Coffee pays a visit. A mobile coffee truck owned by Ryan Voeller of St. Cloud, Adventure Coffee, has made âHoliday Cheer Cups for Medical Workersâ a part of its online catalogue this year. Most days, for $5.25, anyone can purchase online a pre-paid cup of Joe for hospital and assisted living staff members in St. Cloud. Cups can also include a personalized message. Tracy Moe had the idea to bring the Adventure north.
