Сначала босс, а затем механик

My friend Mira and I wanted to buy a new car, but the price was far too big. So we are off to the boss to talk to him about a discount. Of course we had arguments that he could not resist. Mira and I had to hold our holes but we got the discount .We actually thought that we now get the car but there we have the bill made without the mechanic. As soon as we have left the office of the boss, the mechanic walks us over and wants to sink his noodle into us as well. All this just to get a car cheaper...
