Britain's office workers consume millions of cups of tea every year, and the team here at Punchline is no exception. 

Tea is a precious commodity that is highly regarded in every British home and workplace. It is generally considered a revitalising elixir, and regularly assists in forging friendships, repairing relationships, allying colleagues and acting as an adhesive that binds Britons together.

But what are the top ten essential dos and don'ts for making the perfect colleague cuppa?

By following LondonOffice.com 's simple rules, you can ensure that your tea-making etiquette is tip-top, and avoid any tea-induced office feuds.

• DO make a round of tea, not just a cup for yourself. Don't deny your colleagues their brew. Not only is it rude to just consider your own needs, but you will turn your whole office off the idea of making tea for you too.
• DO remember your colleagues' tea order. Strong, black with two sugars or weak, milky with no sugar? Wise up to your colleagues' tea preferences as there's nothing worse than a mismatched brew.
• DO make sure de-caf options are available. Some people do prefer their tea de-caffeinated, so don't alienate them from the office tea-making rituals.
• DON'T queue jump to the kettle. Is the kettle already boiling away with an array of mugs neatly lined up beside it? Just pop your own mugs to the side and go back in a few minutes. There is simply nothing worse than a boiling water thief.
• DON'T put a wet teaspoon back into the sugar pot. Another office tea-making crime is being the person that causes those horrible, discoloured clumps of semi-dissolved sugar to form in the jar.
• DON'T use someone else's mug. Brits can be extremely territorial over their mugs and cups. Chances are each person in your office has spent years searching high and low for their ideal brew holder, so don't take it away from them.
• DON'T stir cups of tea with anything other than a teaspoon. Knives, forks and pens simply won't do. You need the correct equipment to create the perfect brew, so make sure a clean, dry teaspoon is always to hand.
• DON'T try to carry multiple mugs at once. Not only will you be wasting precious tea as it inevitably splashes over the sides of the mug and onto the floor, you're also running the risk of dropping the whole lot altogether, which would be catastrophic.
• DON'T hand over a mug of tea that's dripping at the base. Avoid the unsightly mug stains on your desk and take the time to quick wipe the bottom of each mug before handing it over. Your colleagues will thank you in the long run.
• DON'T cough or sneeze into the mug. If you're suffering from a cold, hand over tea-making responsibilities to someone else. There's nothing worse than seeing someone cough and sneeze over the mug you're about to drink from. Bleurgh!
