Calling a wrong number

it was a real surprise: I typed the numer of a cinema, beginning with the city code (it’s in Germany, where I also live), klicked “Connect” button and suddenly I heard the voice of my mother-in-law, who definitely does not work in the cinema. After finishing I checked the log: there was in fact the number of my mother-in-law (who lives i another country).
I tried again - typing the number… when pressed “Connect”, the number suddenly changed to my mother-in-law’s contact, so I cancelled it.
The next time I typed the number again, but starting with country code of Germany. Now it worked as expected.

Anybody else with similar surprises?
