    Refer to the following complaint letter written by Bryan and attempt the next 2 questions.


    I was at the Chomp's outlet at Bukit Panjang Plaza on Monday at around 4.30pm and ordered a coffee while I went through my textbook. The outlet manager came to me at around 6.30pm and told me that I could not study in the restaurant and had to leave.

    I wonder how Chomp's defines 'studying'? Does it mean that customers are not allowed to read? Would another customer holding a book in his hand reading for hours be told that reading is not allowed? Would another customer who is having his coffee and surfing the Internet be told that that is not allowed?

    I fully understand that the restaurant has to enforce a “no studying' rule so customers do not deprive others of seats, especially during peak hours. However, it was unreasonable of the outlet manager to assume I was studying. In any case, I had not finished my coffee and there were many empty tables around anyway. Also, there was no notice in the restaurant to state that reading or studying was not allowed.



    Which of the statements below best describes the MAIN problem of the “no studying” rule, as highlighted by Bryan in the above letter?


    • The problem is that the ban on studying is unfair to students who are customers too. 
    • The problem is the lack of a notice to state that studying is not allowed. 
    • The problem is the outlet manager who was rude and inconsiderate. 
    • The problem is that there could be different interpretations of “studying”.

    (III): The manager thinks that Bryan is studying because he is surfing the internet.

    (V):  The manager requests that customers do not study in Chomp.
