Question about new VAT / dining tax changes

Hey guys, I saw recently that apparently the taxes for eating inside a store changed and are now equal to when you take your food with you on the go? I decided to eat inside a train station bakery today. I had just a Laugenbrötchen so no drinks or other items. The takeout price is 4 euros, but I was charged with 4,80 something for wanting to eat it inside the bakery which I found odd. They also still had the two different prices on all of the signs. Now I am wondering if I paid too much? The new rules kinda confuse me. Are bakeries maybe an exception? I thought with the decrease fom 19% to 7% that at least the prices for takeout and eating at the store would become the same?
