The guys that drink protein shakes but have absolutely no muscle tone to support. Tip - go to the gym, actually lift something very heavy, do this lots and lots, then worry about how many grams of protein to consume.
Phones on silent, but that are still on vibrate so everyone can hear it. Turn it OFF.
Presentations written on a massive apple mac desktop, 6" in front of the author with lots of tiny text, that when presented on the small TV screen at the far end of the meeting room cannot be read by anyone. Audience and environment awareness - acquire some. Please.
Women with no circulation who are perpetually freezing and insist on having the office at 26 degrees whilst everyone else has see-through clothes through sweating. Put a bloody jumper on or some thermals.
Mobiles with sampled music as a ring tone and left on far too loud, that they leave to ring a good few seconds longer than necessary just to make sure everyone can hear the full first verse of Dancing Queen before answering.
Text alerts that say "Warning, it's the wife!". That wasn't funny the first time, many years ago.
Sorry smokers, but coming in from your fag break absolutely reeking of fags and making the office stink to the point it actually catches on the back of other's throats. Oh, and then hanging your fag reeking coat on top of the coat of a non-smoker so that their coat stinks to high heaven. You stink. You really, really stink.
Eating a packet of crisps then deciding to type something on my keyboard leaving all the keys glistening with grease. You're a pig.
Adjusting my chair. Stop it.
Arriving at 8.59am, chatting to a few people on the way to the coat hooks, quick chat at the coat hooks, nip to the loo, back to the kitchen, quick chat, make a brew, another quick chat, wander to your desk, stopping to chat with half a dozen people on the way, sit at your desk, phone your sister, have a quick chat, nip to the loo again, back to your desk, have another quick chat, then at 9.43am start work. Then go for a break at 10am. I've got a written log of this over a 2 week period and the next time you make a catty remark about my clothes, it's getting submitted to HR.
