The next sentence: De segundo, un filete con patatas fritas, por favor.
You make a show of pointing at your watch for the waiter (de – from the German “demonstrativ”) and see a second hand that was originally made from a tin. But it is not “sekundo”, it is segundo – so the hand is very soft (segundo – the German “Dose” means “tin”). The waiter is a little annoyed at being summoned like that (un – from the German “ungehalten”, “annoyed”).
You order a fillet with tea leaves on top (filete), with jam next to it (con). Then come the chips: your dad makes them, always in the shape of piano keys, and puts them in a cup (patatas – from the German “Papa”, “Tasten” and “Tasse”: “dad”, “keys” and “cup”). He fries them in that cup as well (fritas – “frittiert” means “fried”), and then everything floats out through the gate (por favor).
