At IKEA, you pick up what you want, take it home, and screw yourself

I was in Ikea checking out some furniture and my buddy brought a table and an office chair. While settling for the delivery bill, he was asked whether he want those furniture assembled for a small fee.

To my surprise he approved seeing that he doesn't have a screwdriver at home. I stood there flabbergasted. Isn't Ikea famous for their supposedly value-for-money products that require allegedly simple DIY steps to piece the furniture together?

What's the point of buying DIY goods and then get someone else to assemble it for you? It's no different than a daddy buying Lego for the son and then gets the uncle to build the spaceship so that the son can play with it.
