This gives a new meaning to the expression "Night Clubbing".

It's bad enough that many of these guys (many of whome are not bachelors - they have wives and children back home) are away from their loved ones for months if not years at a time, put up with dreadful working and living conditions, are often paid in arrears (or not paid at all)... Believe it or not, some of these "bachelors" even have to pay a hefty bribe to a recruitment agent, in order to get the job in the first place.
