They often do multiple annoying things which proves that they're fucking thoughtless cunts.
• not turning the shower off properly so it remains dripping, loudly, until someone else does the honours. how can you not notice this as you're drying yourself you fucking twat.
• leaving shower gel/shampoo containers just on the floor of the shower instead of stood up vertically around the side.
• not clicking the cap of a shower gel/shampoo closed again after using it. nice one - diluted shower gel/shampoo. how hard is it to click it shut? blows my mind. you might as well pour it down the plughole. inexcusable.
