Ah! See people wey de use scope buy food. Be like una plenty like this😅
But I can agree that it works. My own is, if they tell me price(not for food, of course), I go, "shey if I price, you no go carry stick pursue me." It always makes the trader laugh and puts us both at ease.
As in ehn, if you can make them smile a little, you've made your negotiation about 30% easier.
