Grandpa Jupp's secret

Grandpa Jupp liked to drink beer, but Grandma Henni was against it. So, there were always arguments until they both agreed that Grandpa was allowed to drink exactly one bottle of beer a day. So, every day, Grandpa would go out with his shopping bag to the kiosk to get his bottle of beer. Arriving at the kiosk, Grandpa would order a beer from Karl , the owner of the kiosk, "Kalli, hömma, gippsse mich mein Bier? " ( Karl, would you please give me my beer ). And Karl put a beer bottle in the bag.

Grandpa had a secret appointment with Karl , which of course nobody was allowed to know about, and so Karl packed He secretly added one, two, or three more bottles. Then he gave the bag to Grandpa, who took it home.
On the way he passed the allotment garden where Grandma was weeding. "Show me what you have in that bag." And Grandpa showed that there was exactly one bottle of beer in it and nothing else. Grandma let him go home unchallenged.

Once there, Grandpa unpacked his bag and had 1-2-3-4 bottles of beer and he immediately poured himself a glass.
Cheers! – but don't tell anyone...
