1) I only mentioned the overheads as a point for comparison in my arguement for oversaturation, before looking into the facts with actual real documented figures,
2) I did not "pick" Orlando, Florida, it came up as the most dense quantity of McDonald's restaurants in the given area but to justify the validation I also divided the total number of US restaurants by the total US population and worked with those figures to give a more "real world" average scenario.
3) If you looked at the link that I provided so you could exam the context of the figures I quoted, you would see that the Orlando scenario was based on the number of restaurants per 100,000 people. What I do not know is: if these figures take into account transient people such as tourists or the regular static population of the area. I assume the later, but even so my final conclusion was based on total US restaurants divided by total US population.
4) I have not mentioned the cost of the overheads in Denmark, because I do not know the costs. What I have implied is, if it takes 3 US restaurants to service the same amount of customers that the 1 Danish restaurants serves then it attracts 3 times the amount of overheads, not that the one US restaurant attracts 3 times the cost of overheads of the Danish restaurant.
Let me elaborate.
3 x USA McDonalds restaurants each with a total annual overheads of $100,000 (example) per annum,
therefore 3 McDonalds restaurants with overheads totalling $300,000 (example) per annum to serve 69,600 customers, based on the amount of total McDonalds restaurants in the USA (14,146) divided by the total US population (328.2 million) so, 3 x 23,200 = .
for simple math let us presume that the overheads are the same or marginally similar,
so,
1 x Danish McDonalds restaurant with total annual overheads of $100,000 serving 65,235 people, based on 89 McDonalds restaurants in Denmark, Greenland AND the Pharoe Islands divided by the Danish population (alone) of 5.806 million people.
Ultimately the one Danish restaurant is servicing 3 times the amount of potential customers compared to it's US counterpart.
