Don't make me regret coming with you!" Ahmed was sitting with his friend Karim at the coffee shop when Karim said to him: — "Hey man, are you free tomorrow? I want you to come with me on an errand." — "What kind of errand? Come on, tell me, are we walking into a surprise?" — "We're going to buy a new mobile phone, and I want you to haggle with the guy because you know how to get the absolute best price." — "Consider it done, my friend, but just make sure you don't get me into trouble!" The next day, they went to the shop, and as soon as Karim saw the mobile phone, he said: — "Oh! This is a masterpiece, how much is it, mister?" The shopkeeper told him the price, and Karim looked at Ahmed and said: — "What do you think?" Ahmed replied: — "Man, this is way too expensive! Do you think you're buying an airplane?" Karim laughed and said: — "Well, why don't you negotiate with him, man? Why are you just standing there?" Ahmed started haggling, and the shopkeeper kept saying: — "My friend, this is my final price, I swear I'm losing money at this rate!" Ahmed told him: — "Come on, cut the talk, we're not buying from the market for the first time. Give us a good price so we can wrap this up." After half an hour of bargaining, the shopkeeper dropped the price, and Karim agreed instantly. Ahmed looked at him in disbelief and said: — "What is wrong with you, kid?! All that haggling and in the end you agreed right away to the price he first offered?" "Damn you! So I'm the one who got worn out while you're the one having fun? I'm never coming with you on another errand again!"
