Please imagine someone is insisting you do something (e.g., going somewhere or trying something, etc.) that you dislike for certain reasons. For instance, at the place they want you to go, there is someone you don't like or what they tend to have there smells bad to you, and so on.
What structure is used normally in English to indicate the message below?
(Go /eat, etc.) just as a test this time and afterwards if you feel it’s bad, don’t (go/eat) anymore.
This is an exact translation from what we say in our language. I'm sure it makes good sense to you, but what about its possible grammatical and structural problems?
