It’s legal to buy things with cash. What would you be reported for?
Of course if it’s fake cash, that’s illegal, but real cash is legal tender, and must be accepted, if it is reasonable.
Buying 1.50 chewing gun with a 50eur bill? The shop does not need to accept it.
Buying an item that costs 400eur using two 200eur bills? Perfectly reasonable.
