The Startbucks cup in GoT was probably staged

I'm sick and tired of seeing this cup every 5 posts on every single existing social platform on the internet.

I couldn't sleep last night and stumbled upon another post on reddit about the fucking cup and I thought of 2 things:

1. Starbucks got more exposure out of it than they would have gotten from 5 Superbowl commercials
2. How in the fuck do you miss a fucking cup that's perfectly aligned front-facing the camera in a room where there are at least 50 people - then another at least 10 people that grade and edit it don't see anything out of place.

I get it, it's a dark room - but you still color grade the scene - you look at the details.
But firstly what the fuck was the script supervisor doing?

I don't personally watch the show, I don't give a flying fuck if there's a limited edition coca cola bottle in the middle of the scene but in my opinion to think that this thing is not staged it's a really really long stretch.

What are the odds?
idk, but they're low..

So was it 100% staged or just a mistake?
I don't know but I'm more inclined to go with the obvious here and I'm looking forward to stop seeing these "news" everywhere.
