Stuffing shit in used crockery.
A chocolate biscuit wrapper plonked in a near-empty coffee cup, a wadded up serviette / kitchen roll / snot rag floating about in the remains of your soup, a banana skin abandoned in the milky unpleasantness that was once a bowl of ice cream, etc etc.
What’s the thinking here, what do you suppose are the next steps? I’ll tell you what the next step is, some other poor **** has to fish around in your effluvia to retrieve your crap, be that restaurant staff or me or whomsoever is cleaning up after you. And do you really think this vegetarian wants to rummage about in what was once prawn linguine in order to excavate half a dozen Quality Street wrappers? You’re literally creating work for no reason and it’s grim work at that, ****ing stop it.
