what would you do, archery shop sells you wrong handed bow, twice.

[openfire]

A friend of mine here in cochrane, just realized he is left eye dominant, a week after buying a high end bow from a reputable bow shop. (I am intentionally being vague)

When I met him he had already had a bow he bought from them but he didn't really shoot, I got him back into it in January, he found he was a natural but his bow was about 5 years old, so he went back to buy the newest a greatest thing on the market.

He has been having trouble with it and after doing a you tube search this morning, on setting up the bow realized they missed a step with him, the eye dominance test.

What you would do in his situation? Should he have done his homework about that before buying?
