Dem tear my eye for Onitsha Market

I went to onitsha market (Emeka Ofor) to fix my laptop’s screen, the guy I met said he wasn’t having the screen at that moment and asked if I could wait.
I was on my way to Enugu and there was no way I could wait, so we agreed he should buy the laptop. We agreed on 30k, a laptop I bought for 104k that only had inks on the screen and all i intended was to buy a new screen for it.
Like the 30K price wasn’t bad enough, I agreed only for him to tell me he was going to scan some internal faults of the system and he said he was going to charge 10 naira or so per unit. I didn’t see the 10 naira as issue, after he was done scanning my PC, he told me the total charge for the scanning was 19k. I don’t know how he did it, but he showed me everything on his screen. I couldn’t argue with him because there were plenty scary looking guys around and that was my first time there. This guy sha paid me 11k for my brand new HP15 that only had little black inks on its screen.
