If you want real customers and you would use your product, then just be yourself on the call. If you swear, swear, if you’re polite, be polite, if you wear suits, wear a suit, just be you. 

If you’re not you, and you get the sale, the customer sucks, you bought them, or the product sells itself in which case, good job. The other two are going to zero

I completely agree with you. In the end, being authentic is the only way to get real customers. Any result you get from pretending won’t last. Honesty really is the best approach!
