This is not a drill.
It's an actual verkaufsoffener Sonntag.
In Lidl.
In Munich.
Had to read the sign 5 times before I believed it.
The affected branches are the Central Bus Station/ZOB, Schwantalerstr., the other one in Westendstr. and another one (sorry, the address has gone, but it's the four closest to the Wiesn). Posters in-store confirm this.
Happy shopping!
