There are always queues at filling stations not for fuel but for air. Air is free. Some people have an air fetish and line up everyday to get FREE air. The boy who fills up air in tyres has the toughest job on earth. It is demeaning low paid and people are rude. Gas stations are governed by the ministry of petroleum which is very strict. Special messages prohibit customers from tipping. Luckily most people still tip seeing the plight of the air boy.
