The barman stopped. He looked the man dead-straight in the eye, swatted a passing fly, then said; "Amigo, if you drink these bottle of wine, amigo, I give you these… another bottle of wine amigo…"
The amigo stopped. He chewed slowly on a piece of straw hanging out the side of his mouth, spat on the dirt floor, then drank the bottle of wine. The amigo looked back at the barman and said "Gracias for these wines señor"
Then he rode off.
And that's it. There is no more to this story because, according to another story, tapas weren't invented until hundreds of years later when a king was supposed to eat little dishes with his wine between his meals.
