Ripped off abroad

My interaction with a street merchant:
Merchant: Those are nice glasses. How much did you pay for them?
Me: $3
Merchant: Can I wear them?
[I give him the glasses]
Merchant: That's a nice hat. How much was it?
Me: I don't remember. Cheap. I got it in China.
Merchant: Can I wear it?
[the merchant is now wearing my sunglasses and my hat]
Merchant: I'll trade you anything I own for these things
Me: No. I need those things back or I'll get a sunburn.
Merchant: Where are you from?
Me: Chicago
Merchant: I'll be back. Have you ever met him?
Me: Schwarzenegger? Nope.
Merchant: (obviously dissapointed) Oh. Ok. Well look at this box. Do you like it?
Me: It's a nice box.
Merchant: Ok. I will write down how much I want for it. Then you write down how much you will pay. Then I come down like a Masaai from a tree and you come up like a lion from the bushes.
Me: I don't have any money.
Merchant: It's ok. Just for practice. My first price is 18,000 shillings (US $2,500)
Me: I don't know where to start.
Merchant: You have to be a hard bargainer. Start low.
Me: 1 shilling.
Merchant: You are a funny man. Because you look honest I'll give you a better price. 12,000 shillings (US $1650)
Me: 500 shillings
Merchant: American dollars? 500 American dollars?
Me: No.
Merchant: Ok, you are getting better. I will now reduce my price to 5,000 shillings.
Me: 1,000 shillings
Merchant: You are crazy. I will give you my final offer. 2,000 shillings. I can't go any lower.
Me: 1,700 shillings.
Merchant: Ok. Now what if you give me that hat as well, what will you pay then?
Me: I need that hat or else I'll get a sunburn.
Merchant: But supposing you did...
Me: 1,000 shilllings.
Merchant: Sold. 1,000 shillings and the hat.
[He starts wrapping the box up.]
Me: I thought this was just for practice. I seriously don't have any money. I have 100 shillings and I need it to take the bus home. Can I have my sunglasses and hat back. I don't want to get a sunburn.
[I meet up with the rest of the group. I find out that another merchant offered a girl the same box for 700 shillings as his starting price and gave her a free gift.]
