I found a Real Madrid shop at the Barcelona Airport!! How the hell is this even allowed?!

Soo my days in Barca are over, next up - visiting my home in Slovakia after half a year! I booked a superearly morning flight from Barca to Vienna soo I can have one meeting in Bratislava about my future life & plans & stuff :D And as you know, early flights come with early alarm and kinda stress..at least for me.

What made the whole morning even crazier was the Real Madrid shop at the Barcelona El Prat airport! Whaaat the heck! I mean...it has to be the biggest rivalry between clubs ever! How the hell would any people in lead of the Barca airport allow this?
