The given argument is from a memorandum of business manager of Happy pancakes restaurants and is basd on customers' response on replacement of butter with margarine in the restaurant.The author said that as the butter is replaced with margarine,only few percent of customers complained about this change and most of them just accepted margarine in their dish when served without arguing.So the author thinks that customers don't distinguish between butter and margarine or they call margarine as 'butter'.This argument may look cogent on first look,but is fundamentally based on weak facts,fails to present evidences from reliable sources and assumptions;therefore author exacerbated the argument.

Firstly,the author stated that the change of butter to margarine has affected very little customers on the basis of customers complaints recieved,but customers complaints isn't the most reliable source to conclude that.It is possible that there might be 500 customers coming to restaurant every day,but only about 30 to 50 customers give feedback or complaints.So in such cases the manager can't assume that the change has little effect on customers,instead he should have made some survey by asking every customer by insisting them to give feedback about this change and therefore accounting opinions of all customers.This survey could have strengthened the argument.

Furthermore,the author stated that many servers said that customers don't bother if they are served with margarine instead of butter,but it is possible that those customers might be enjoying the main dish so much that they are indifferent about adding butter or margarine in that dish.Instead the manager should have told servers ask the customers about why they aren't bothered with margarine and servers should have noted what dish customers eating and all details required.Such major details missing in the argument weakens the argument.

Similarly,the author further have assumed that the customers don't distinguish in butter and margarine.Making such assumption on the basis of unreliable facts stated by author in recent sentences wouldn't be wise and might affect the restaurants business in contrary manner.

On conclusion,the arument does stated some facts that change from butter to margarine isn't making any difference to customers and customers happily accepted the change,but the author fails to substantiate his conclusion by presenting information and facts based on unreliable sources like customers complaints,report from surves etc.
