Wishful thinking, mate. In real life, does the pro shop owner let you take a couple of clubs home in order to try them out before you buy them? I don't think so.
Actually, while may not let you take them home they do let you try them out.
The purchases I have made of real clubs have never been made without testing the clubs first, either on a practice range or at the very least in a net. Larger golf stores often have 'tester' clubs for this very purpose, otherwise club heads are protected with a bit of tape to prevent marking but allowing you to get a feel for the club.
Think this would be a great addition, in parallel to the obvious need for a driving/putting range in the first place. However, if you have to pay to test new clubs it would be no better than current rental option.
