It's a terribly hot day and you have to go grocery shopping. The supermarket was 15 minutes away, but it felt like hours in the desert sun. As luck would have it, the air-conditioning in the supermarket was broken, so you had to suffer even more, wandering through the rows with a basket in your hands.

Having collected everything you needed according to the list, you went to the checkout and almost exploded with anger, looking at the huge queue in front of you. There was only one cashier working, no one reacted to your requests to call the second one. Resigned to your fate, you waited patiently for your turn.

On top of that, you began to feel someone breathing down the back of your neck, directing warm and irritating streams of air. ‘Who do you have to be to breathe like that?!’ you thought to yourself, clutching the handles of the basket with anger.

You turned round to tell the jerk with the huge lungs that he was breathing too deeply and disturbing your comfort. Behind you stood a middle-aged man in a military uniform, with a thick beard and moustache. He looked down at you, staring impassively at your furious expression.
