How to deal with people that want free beats?

I'm pretty sure I've got my first real customer now, seeing as he asked for my paypal info after being really clear about which beats he wanted and what changes he'd need done to them.
However before this guy I had dudes seriously wasting a lot of my time like this;

I went off on this guy and ended up calling his bullshit when he told me that he'd spent $1000 on his project already but for some reason couldn't afford $10 for a professional quality instrumental which he had already said he wanted for sure.

I don't like how I handled it looking back, he was an asshole and a time leach but I could have simply said;

"I do hope your financial situation improves, when it does be sure to contact me again and we can get started on your project."
