In the same year, Kroc also established his company under the name of McDonalds Corporation. As with any business, Kroc endured many trials and tribulations from the time he opened his business. One of the main improvements made was to make restaurants suitable for the northern climate. Many upgrades had to be added to the company to ensure its long-term stability. A basement has been fitted out to house heating, air conditioning and a ventilation system. Ventilation was very important because it had to produce warm air in winter and cool air in summer using exhaust fans. All the measures taken to improve society are now bearing fruit. McDonald's is now considered a top five fast food restaurant and has become a staple of American food culture. Overall, as an organization, McDonald's suffers from widespread internal problems. Many issues range from providing the best value to marketing to customer service to even simplifying the menu, all of which have created challenges for this business. Among all these concerns, the main problem the company faces is actually customer service: McDonald's is a global company that meets the hunger of millions of people every day. (Lutz 2013, Internet
