I know the drivers will come to pay since I have their license numbers. But they put me in hot water before they come to settle their obligation. Another frustrating aspect is when vehicles are lined up at the station waiting to be served. Some drivers don't have patience at all. They begin to blow their horns on you as if you are the cause of the long queue.
Some drivers cause problems in paying for petrol.
Problems in getting change also contributes to such queues forming. I become very nervous when that happens. The long hours of standing on your feet to supply vehicles is another difficulty. My legs begin to ache painfully. I am gradually overcoming this pain but when I started this job, it wasn't easy at all.
