if shopping doesn't make you happy, you are in the wrong shop
I never heard about it but today I read and I think it's a logical statement.
Another thing is, you have to be an expert in negotiation to be able to make a good deal on your shopping.
In Bangladesh negotiation skill requirement if you want to buy things at a cheaper price. Still, now I have the skill and but for it, I need to be updated on the actual price of the product which I try to buy.
At last hope, you enjoyed the food well.
