Self Service Refuelling

Self serving refuelling has been a key innovation of our modern society. Self Service refuelling is an effective way to protect gas station attendants from a heatwave. This can be an effective way of ensuring that motorists have the knowledge to pump fuel themselves. It is therefore important to develop guidelines documents as well as videos to guide self$-$service fuel.

For much of the world, where self$-$service refuelling is an accepted part of motoring life, this will seem very strange. Johannesburg isn$$t alone in barring customers from picking up a petrol or diesel pump, though. You are required to develop an application to guide motorist with self service refuelling.
