Here is a riddle for you, ayahav:
A man goes to a supermarket. He buys a whole lot of stuff and when he gets to the cashier, he asks:
“Would you mind if I paid you with a cheque from out of town? You see, I do not live here.”
The cashier replied:
“It is Ok, but could you please write you address and telephone number on the back of the cheque?”
“No problem”
The man proceeds to write the cheque, turns it over, writes his address and phone number, and underneath draws three tiny triangles, followed by three dots.
The cashier looks carefully at the cheque, looks at the man and says:
“ You are a sailor, aren’t you?”
Then man smiles and say: “Yes, indeed I am”
Here is the riddle: How did the cashier know the man was a sailor?
(Answer tomorrow)

Best wishes,
Bernhard.
