Charity scammer low life [closed]

What would you call someone, with money, who attends an all inclusive fund-raiser, refuses to pay the attendance fee, and sends his girlfriend up to the bar all night to get him goblets of wine while he listens to the band? BTW, the GF paid up her end of things.

Solution 1:

Ligger

From UrbanDictionary:

An individual who attends parties, openings, social gatherings and events with the sole intention of obtaining free food and drink - an arch blagger.

Popularised by the NME in the early nineties and possibly with it's entomological roots in the fishing term for "baited line".
