Office Annoyances

I've been meaning to do this one for ages, but today I was more annoyed than usual:

• Colleagues who use the last of the water, but don't change the bottle on the cooler.
• Colleagues who take stationery items that they don't need, never use, and know someone else ordered specially, just because the items are interesting.
• Colleagues who join us for lunch and insist on individual bills when it saves them money, but never when they have eaten or drunk more than the others.
  
• Staff who go for a cigarette break within 10 minutes after clocking in or before clocking out.
• Staff who are always present when their boss is around, and never present when the boss is out.

That's just the tip of the iceberg. I could go on for ever, but it wouldn't be very original.
