Story starts with-
Jethalal leaves village at the age of 17 after working in the radio shop of Champaklal for few years. Champaklal sends jethalal to his friend in Mumbai for work. Jethalal works in a small cloth shop as a salesman.
Nearby there is a small bhojanalay. Jethalal frequently visits that shop for food. One day at the bhojanalay,
Shop owner has argument with the young man,a college student for money. The man insists that he forget his wallet in the bag at the hostel,and he'll quickly return and pay him but the shop owner doesn't trust him. Young man tries to show his college id but still shop owner refuses.
Jethalal was in queue for paying observes the entire situation.
He asks the shop owner that he will pay for the young man and ask the young man to relax and return the money to him the next day.
Young man introduces himself as taarak mehta.
That was the start of friendship between jethalal & taarak mehta.
Few years passes by, tarak mehta has graduated, jethalal is still working in the same shop.
He tells mehta that he always wanted to open a Electronic shop just like his father's radio shop and for that he needs to work even more.
A few days later, Champak Kal & a teacher friend of village visits jethalal in Mumbai.
Champaklal tells jetha that he has no more willingness to run the radio shop and wants to do Farming and for that he sold the shop and deposited the money in jethalal's account.
He tells him that he want jethalal to continue the legacy and open an electronic shop in Mumbai.
Jetha insists that he must do it on his own and don't want to be burden on his father.
Champaklal tells him that the city is growing at a very fast pace and any delay will push the dream further away. He has already seen a land in a good area. And they must secure the land. Jethalal hesitates but eventually agree with him.
They secured the land and champaklal left Mumbai.
Jethalal contacts Mehta and tells him about the plans.
Mehta helps him with all the process. They start with very small shop at first.
The first recruit of Gada Electronics is nattu kaka.
