Hi Asha,
Good presentation, but with a specific scope. I mean, this is okay if the client or target audience is "Americans," but you are using the term on slides as "International clients." Whereas, the phrases or words you are mentioning, which should not be spoken or are wrong, are okay for Americans but not internationally. Most of the words and phrases are from British origin. We in India, the masses have undergone the British education system, so there is no WRONG as such. It's only that it cannot be implied on everyone, especially with Americans.
Good work.
Thanks.
