How can such an error go unnoticed? #TheFrootiLife

Recently, Parle Agro launched their new #TheFrootiLife campaign for Summer 2018 featuring Alia Bhat.

In one of the advertisements, the tiny male character tries to woo Alia with different things such as money, diamonds or even a cat which she finds cute but still refuses his proposal.

So the male character is shown converting a mango into a drink which is indeed Frooti. He offers it to Alia and then she accepts and drinks Frooti with a smile on her face.

If you observe closely, when Alia takes a sip of the drink (for close to 2 secs), the level of frooti in the bottle does not reduce. Does this mean, Alia Bhat has not even tried taking a sip of Frooti?

The advertisement clearly says that if you want to impress someone (Alia), then rather than giving money, diamonds or other expensive gifts, give Frooti. But if the lead character in the advertisement who endorses this product, is not even drinking Frooti in the advertisement which can be clearly seen, then what’s the point of showing Alia Bhat in the advertisement?

Here is the video of the TV Commercial.

This Ad was launched in April, 2018 and according to the reports, Parle Agro has spent around 100 CR on this campaign. I tried contacting the marketing team of the Parle Agro, but didn't get any positive response from them. The Ad is still being shown and even after four months, there is no change in the advertisement.

In my opinion, after noticing the error, they could have either made some changes in the quantity of the drink in the bottle or simply cropped the bottle from that frame.

What do you think a brand should do after noticing such error?
