A pint of milk

John has moved into an apartment close to a new store. John walks in late at night and asks for a pint of milk. The store owner gets angry as clearly they don't sell milk. "Fuck off chap we don't sell milk in here" yet he persists for the milk. So the store owner beats the crap out of him and John ends up in hospital. He gets out the next morning and goes about his day. Later on that evening John goes into the same store pestering for a pint of milk again. Store owner doesn't hesitate in beating the crap out of him this time. Again John spends the night in hospital. The same thing happens twice more but the last time the store owner says to John "come in here asking for a pint a milk again and I'll nail you to the floor" so the next evening John is back in the store. John asks "got any nails mate" store owner "no" quite angrily. "Give us a pint of milk the mate"
