I have encountered a question related to wish clauses. According to the answer key, the answer must be like this
I wish you had not bought a camera already as my cousin works in a camera shop and can get up to twenty-five percent staff discount.
But if it is used this way, there is no regret. Do you think that the following sentence more accurate than the above?
I wish you had not bought a camera. As working in a camera shop, my cousin could have got up to twenty-five percent staff discount.
