To Advertising with Love: Failed Marriage Proposal in Dubai??

Dubai's social media rates are high up in the air right now for the said to be a marketing trick my Cadburry. Is this true?

I have read and read and read almost everything I could find on this topic and came to a conclusion.
No. The proposal was not held in Dubai.
Secondly, no it's not a marketing trick by Cadburry, the train happened to be passing through with the Cadburry signs on it.
Journalists still don't know whether this was scripted or not but something just occurred to me. If it wasn't scripted then why did the woman filming this film it before the couple reached the singers, and why is there only one video being posted, If a proposal was happening don't you think others would be filming too?

Also, the girlfriend turned around held a guitar and hit his head with it, and he fell right to the ground, I don't know if that was real or not, but I didn't believe it.

Now this video was not held in Dubai, on the other hand it was in Mumbai, India, however reasons to why Dubai is on the title of this video is unknown but rates are increasing by the second so HOOORAY for Dubai.

Overall, the video is absolutely HILARIOUS, and the lady filming is even funnier.

Anyways here is the video
