I’m not sure if they are still running this advert, I meant to comment some time ago but didn’t get around to it however, better late than never.
As you will see it is an advert set in the UK with both characters speaking mostly The Queens English, except for the one phrase in the middle which definitely was not English.
The story as you will see is of a young man going for a job interview who stops on the way to have breakfast in McDonalds on the way.
Upon entering the restaurant he walks towards the screen to purchase his food and allows a woman who appears stage left to go in front of him, so far, so good.
When the young man gives way to the woman he utters the phrase, “it’s all good,” when one might expect him to use the English phrase, “after you,” which to me makes a lot more sense.
I imagine “it’s all good” may be an American expression although how on earth it translates into “after you” I have no earthly idea, answers on a postcard as they used to say!
