Screw them

These delivery people need to get their behavior right. What the hell do they think of themselves? Man, you have come to deliver a product to your customer's house, have some courtesy. Your behaviour continues in this vain, and your customers will dwindle, thereby leading to a cut in your freaking salaries. We shall see who says goodbye to whom and doesnt get a reply then.

Get your behaviour right, will only help you in the future! :@
