Naughty Funny Moment

There was a particular resturant that i always go for launch to eat amala, and there was also a white man (oyinbo) that also go to this resturant so i discover that whenever this white man finish eat, he always shout 'hey', i was so confused because i don't know what really makes him shout whenever he finish the food.
So i think to request for what he always. I asked, and they said it is chicken and wine, so i ask for it, i finish the first plate and i didn't shout 'hey', so i ask for another plate and i didn't shout hey, i was like 'this white man is crazy o, then what make him o?' so i ask for the price and they said, The First Plate Is #80,000 and the second plate is also #80,000.
Then I Shout "heeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeyyyyyyyyyyyyyyyy'
