How to bargain when shopping?

Xiao Li: Boss, how much are these pants?

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

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

Boss: Don't look. Everything is good. I'll give you a discount 170 yuan.

Xiaoli: Is this also called a discount?

Boss: Hehe, ok, 140 yuan, it's ok this time.

Xiaoli: Ha ha ha ha, I smiled!

Boss: What are you laughing at? Is it too expensive?

Xiaoli: No, it's more expensive than that. It just pumped my blood with a pump!

Boss: No exaggeration. If you are local, it is 120 yuan.

Small pear: ...

Boss: You won't be too expensive, will you? I can only earn you a few dollars at most.

Xiaoli: No, I didn't say expensive. This pair of trousers is worth the price.

Boss: You really have sunshine. Buy it quickly.

Xiaoli: Pants are good pants, but there are only a few tickets in my pocket.

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

Xiaoli: 90 yuan.

Boss: Oh, my God, you must be kidding. You're gonna kill me. Add 10 yuan.

Xiaoli: No need to add. I'd like to give you 120 yuan, but there's nothing I can do.

Boss: OK, make friends, and forget about 90 yuan.

Xiao Li: I won't give you 90 yuan. I'll leave a fare 10.

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

Xiao Li: Of course, I come from far, far away. I have to go back by coach. Ticket price 10 yuan.

Boss: You are a liar!

Xiao Li: I haven't cheated anyone since I was eighteen, believe me. Look at my expression, how sincere.

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

Xiao Li: 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.

Xiaoli: Believe me, I mean it. If I don't eat again, I will faint in front of you.

Boss: I'm unlucky to meet a slick like you. But you really went too far. One minute you have to take a bus, and the next you have to have breakfast.

Are you saying that you are thirsty? Do you want to drink later?

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

Boss: Believe you? Last time?

Xiao Li: Yes, believe me.

Boss: All right, cheer up, 70 yuan.

Xiaoli: I'll give you money.

Boss: Hurry up.

Xiao Li: Wait, look, there is a big hole in the trousers.

Boss: Oh, my God, this is a urinal. You don't know this is a urinal, do you?

Xiaoli: Oh, sorry, my eyes are blurred. But there seems to be something wrong with the color here.

Boss: No, it isn't. It's matte. It was done on purpose. This is called fashion.

Xiaoli: Really? Looks 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.

Small pear: ...

Boss: ok, I'll show you my order ... you see, the purchase date was last week, and the purchase unit was Guangzhou XXX.

Clothing factory, how can these be old pants?

Xiao Li: Oh, I'm sorry I misunderstood, but ... Oh, my God, the price: 20 yuan.

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

Xiao Li: You are lying. Do you think I'm a fool? This is the VAT invoice, which is the price after tax payment. Only these pants.

Worth 20 yuan, but you ...

Boss: Hey, hey ... Do you want to do business? You know, I rent hundreds of facades every day. What can I eat without making money?

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

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

Xiao Li: Money is a piece of cake. It's just that your behavior makes me angry. You have deeply hurt a consumer's heart.

Boss: Is it that serious?

Xiao Li: Don't you think cheating is not serious? If this continues, it is fraud and crime!

Boss: God, it's so exaggerated. In this way, if you put out the fire, I'll sell it to you for 25 yuan and make five dollars.

Xiao Li: What? 25 means 250. You look down on me?

Boss: No, no, just 24.

Xiaoli: There is a 4, which stands for "death". Bad luck. I am superstitious.

Boss: God, there is nothing wrong with 23.

Xiaoli: OK, it's a deal.

Boss: .................
