Well, this is what too much TV does to you! You start recognising the sets of the shows so well, that when the same is used for different shows, you are quick to spot it!
This happened to us when we spotted Ankur Nayyar in a mock bank in Kohinoor that looked uncannily similar to Special Squad's office. What's surprising is that there was no effort on the set designer's part to make changes in the SS set. Aryan's cabin in SS has been turned into the bank manager's office and the door to his cabin that had a hand painted on it, has been left untouched! It's fortunate that SS has gone off-air!
