Total BS. This email has the characteristics of Nigerian scammers.
Staffs and Postition are Available, two mistakes already.
Most likely they will ask for personal details, and somehow try to steal his identity. If not, he will be a “shipper”. Packages will arrive at his house, and he will have to send them to places overseas. Those packages are bought with stolen credit cards.
If it’s not that, then they will send him a large cashiers check for that “mini office” they are talking about. They will say oh sorry we made a mistake and sent you more than necessary, can you deposit the check and send us $2000 back using Western Union. You friend will fall for that, deposit a fake cashier’s check in his/her account, and send them money.
