The word driver is more general - anybody who drives a vehicle is a driver. You are a driver when you are driving your car. Some people work as bus drivers and taxi drivers (the drivers of trains are usually called conductors).
A chauffeur is a person who is employed to drive a car for a private individual. Rich people and celebrities often have chauffeurs so that they do not have to take public transportation, or drive themselves.
All chauffeurs are also drivers; not all drivers are chauffeurs.
You no longer have to know how to bake a cake or cookie to impress your guests loved ones. Just make this caramel cookies and cream milkshake for them and watch them get lost in the world of utter deliciousness.
Im not saying making a cake is difficult. In fact, with my step by step pictorial to guide you, I dont think ANY recipe at least on Foodomania is difficult. shameless self promotion I know.But Im just saying you make this milkshake once and you wont bother looking at any other sweet treat ever again.
