As a German, I frequently enjoy tourists being unable to cope with the speed of Aldi cashiers. They have the possibility to begin scanning the products of the next customer while you are still paying, which adds additional stress if you are not used to it. If it takes you longer than one second to answer the mantra-like "Bar oder Karte?" ("cash or credit card?"), the cashier will stay friendly, but get visibly annoyed, because if you quickly say "Bar", she will actually begin to count out the change she expects you to receive while you haven't even opened your wallet yet (for example, if it costs 17.95, she will expect you to pay with a 20 and count out 2.05) I think Aldi is the best supermarket in the world, but it certainly is an acquired taste :)
