How to bargain?

I hope you understand from this joke I told you that any counter-offer

Customer: Boss, how much are these pants?

Boss: 180 yuan, authentic America, do you want it?

Guest: Let me have a look first. ...

Boss: Don't look, everything is good. Give you a discount, 170 yuan?

Customer: Is this also called a discount?

Boss: Hehe, ok, 140 yuan, ok this time!

Customer: Hahahaha, I laugh!

Boss: What are you laughing at? Is it idle and expensive?

Customer: expensive! More than expensive? ! You're taking my blood! ! !

Boss: Why are you exaggerating? Seeing that you are a local, call it 120.

Guest: ...

Boss: You're not still idle, are you? I can only earn you a few dollars at most!

Customer: No! I didn't say expensive, these pants are worth the money!

Boss: You have a good eye. Buy it quickly.

Customer: pants are good pants, but I have limited money in my pocket.

Boss: How much money do you have in your pocket?

Guest: 90 yuan.

Boss: Oh, my God! You're kidding. I am losing money. I am adding 10 yuan.

Customer: No, I want to give you 120 yuan, but there is nothing I can do.

Boss: Well, make friends, and you can get me 90 yuan.

Customer: I won't give you 90 yuan. I'll keep the fare of 10.

Boss: The fare? What does this have to do with you buying pants?

Customer: Of course, I'm from far away, and I have to take a long-distance bus back. Ticket price 10 yuan.

Boss: You are a liar!

Customer: I haven't cheated anyone since 18 years old, believe me. Look at my face, how sincere!

Boss: Although I can't see your sincerity, I admit that I lost it. You can count on 80 yuan.

Customer: Wait, I have to add that I haven't had breakfast yet. I'm hungry.

Boss: You! God, you've gone too far. You are playing tricks.

Customer: Believe me, I am sincere. If I don't eat now, I will faint in front of you.

Boss: I'm really unlucky. When I meet a slick like you, I have to take a bus and then have breakfast. What else do you want?

Customer: You underestimate me. Believe me, I want nothing more.

Boss: Believe you? Last time?

Customer: Yes, believe me.

Boss: OK, cheer up, 70 yuan.

Customer: I'll give you the money right away.

Boss: Hurry up.

Customer: Wait, there seems to be something wrong with the color here.

Boss: No, no, no, it's matte. It was done on purpose. This is called fashion.

Customer: Really? Why do they look like old pants? It's weird.

Boss: What? It doesn't matter if you insult me. Please don't insult my pants. This is the real thing.

Guest: ...

Boss: ok, let me show you my shopping receipt ... you see, the date of purchase was last week and the place of purchase was a clothing factory in Guangzhou. How can these be old pants?

Customer: Oh, I'm sorry, I misunderstood, but ... God, the purchase price, every 20 yuan!

Boss: Oh, no, no. This is the price excluding tax. After-tax cost per unit, 40 yuan.

Customer: You are lying. Do you think I'm a fool? This is the VAT invoice, which is the price after tax payment. These pants are only worth 20 yuan, but you ...

Boss: Hey, hey, what do I eat if I don't make money in business?

Customer: In broad daylight, Lang Lang Gan Kun, your heart is too dark!

Boss: Hey hey, how about 30 yuan? My good sister, please let me make some money.

Customer: Money is a piece of cake. It's just that your behavior makes me feel good. No, it deeply hurts a consumer's heart.

Boss: Is it that serious?

Customer: If this goes on, it will be fraud and crime.

Boss: Oh, my God, it's so exaggerated! In this way, you put out the fire, and I will sell 25 yuan to you to earn 5 yuan.

Customer: What, 25 means 250? You look down on me?

Boss: No, no, just 24.

Customer: There is a 4, which means "death". Bad luck. I am superstitious.

Boss: God, is there a problem with 23?

Guest: OK, deal!
