yes, 攞男/攞女 = some people want to get jetso/free things from others
Here: this means selling goods to some people but those people often make excuses to get back money (they want to have free lunch) even the goods are in good condition.
Also, some people who wants to buy something cheap, but they want your goods & also your privacy eg your home address, even you tell them the goods could be delivered to a public place to trade
Some people claimed that they want to buy things from you to give/help 綜緩/單親, but actually they lie to you and get cheaper price, then get back money for making some excuses. Or get free things to sell to others
Pls be aware of buyers who want your address to deliver/claim to help 綜緩/單親...結果, 你會後悔和他/她交易; 因他/她就是日夜狂打電話+網上化身很多"人"狂插你, 威脅要報警, 迫你就範
