Former pro boxer Axel Schulz presented the first mask vending machine outside a supermarket in Berlin's Marzahn district on Thursday.
The store unveiled the 'mask-o-mat' machine to ensure that customers wear face masks when grocery shopping.
Those in need of a mask can pay €1 ($1.14) to get their hands on a new face mask.
Schulz said he sympathises with people who forget to bring masks, blaming his forgetfulness on suffering «many blows to the head» during his boxing career.
Schulz added that he finds wearing masks «exhausting» and burdensome,» but encouraged people to wear them for «thoughtfulness toward the others, for others.»
The requirement to wear face masks in supermarkets and on public transport has been enforced across all German states since the end of April. Recent studies, including one at the University of Mainz, have shown the covering of mouths and noses to be effective in slowing down the spread of the virus.
