Apparently the hot thing to do in some circles (and by hot I mean incredibly frugal) is to register for an event, get your free meal voucher, then un-register.
You get to keep your free voucher and can even re-register for the exact same event to get a second one.
Overlooking the fact that it's a fairly shady scam, it's also pretty lol.
How hilarious is it that you can afford to plunk down a minimum of $1,500 (and usually more) to play a glorified lottery (lol mtts), but you're so nitty that an extra free $10 is appealing enough to go through all the effort of registering, un-registering, then re-registering.
Hilarious, yet apparently somewhat popular.
