Answer: An exclamation mark (!)
Explanation:
An exclamation mark is a punctuation mark that is used at the end of a sentence to show emotion or a very strong feeling.
The statement is best written as;
Under a so called latte levy, people could be charged 25p for paper coffee cups!
This is because the statement contains a very strong feeling about the fact that people could be charged 25p, a “so-called” Latte levy.
The writer cannot believe that a charge of 25p is attached to the use of disposable cups just to cut down on waste.
