An Igbo engineer cant find a job so he opens a clinic and puts a sign outside GET TREATMENT FOR 20k - IF NOT CURED GET BACK 100k

A lawyer thinks this is a great opportunity to earn
100k and goes to the clinic...
Lawyer: I have lost my sense of taste
Igbo man: Nurse, bring medicine from box no. 22
and
put 3 s in patients mouth
Lawyer: Ugh..this is kerosene
Igbo man: Congrats, your sense of taste is restored.
Give me 20k
The annoyed lawyer goes back after a few days to
recover his money...
Lawyer: I have lost my memory. I cannot remember
anything
Igbo man: Nurse, bring medicine from box no. 22
and
put 3 s in his mouth
Lawyer (annoyed): This is kerosene. You gave this to
me last time for restoring my taste
Igbo man: Congrats. You got your memory back.
Give
me 20k
The fuming lawyer pays him, and then comes back a
week later determined to get back 100k.
Lawyer: My eyesight has become very weak
Igbo man: Well, I dont have any medicine for that,
so
take this 100k
Lawyer (staring at the cash): But this is 20k, not
100k
Igbo man: Congrats, your eyesight is restored. Give
me 20k

You cant beat an Igbo man
