After a dreamer sent rice and they will tell that Rice is okay and ready to pay Cash (Only Cash) Simply will ask you to pay for charges (Hawala/Moment charges/ security vehicle charges etc). The dreamer don't understand this 'Mode of Operandi' since the target of this team is neither your material nor your rice. They only target for charges you may paid them in greediness. So beware of such deals, be cautious,be careful.

If someone pays you unconditionally bringing cash at your home without asking a penny upfront, then only proceed for it or sit quite securing your hard earned money.

It is just a caution. Not blaming anyone.
