Kim makes a valuable observation, and while I appreciate what your client may be saying, I feel you ought to alert them to the potential for losing what could be a really good sale!

Do they REALLY need this restriction????

(I will continue with the mod, as I've promised it to you already)

Also, a lot will depend on the TEXT of your ALERT MESSAGE. So give this a lot of thought when you edit the relevant languages file.
