It's a bit of a Bill Brysonism (Notes From a Small Island, IIRC)
but the old lie that women are in any way capable of "multitasking" - or thinking about more than one thing at once - is easily disproved if you've ever had to pop into M&S for a sandwich and had to queue behind a couple of them at the checkout. It's almost like you can hear their primitive girl-brains processing:

"Right, so I've taken all of my items out of the basket, piled them up on the conveyor belt and the nice man has scanned them all in. I've taken them at the other end and put them into my shopping bag. Job done. Oh wait, wasn't there something else I had to do? Why is the cashier staring at me expectantly? Did I leave the gas on? Oh fuck! I get it now! Having presented my items, had them totalled and packed them away, I need to give the cashier some money! Now, where did I leave my purse? I'm sure it's at the bottom of this bag somewhere...."

See also: queuing for a bus for 15 minutes and then realising that they need their bus pass only after having boarded with a 30-strong queue behind them, or my personal favourite - getting to the barriers at the tube station and then resting their bag on the side of the barrier while they rummage through it for their Oyster card. With a 30-strong queue behind them.

When women say they can multitask...
... what they mean is they can do something and talk about soap operas whilst they are doing it.

Does that Chelsea programme count as a soap opera?
Because if so, the women in my office can't even do that - everything stops for their weekly witter about what so-and-so said to the other one last night, while I put my headphones in and do some work...

I know the feeling
Was the sole bloke in an office full of women on two occasions. 9am-10am was Corrie/ Emmerdale/ 'Enders recap or hairdressers/ shoes/ boyfriends complaints until they'd all compared notes and settled down to work.

my wife does this with house keys.
And it really boils my piss.

I pull into our driveway and she asks for my keys as its quicker than looking for hers 'in the bottom of her bag'. Well apart from carrying so much shite in there she can't find anything, she's been sitting in the passenger seat with nothing to do but stare out of the window / talk shite / fondle her crackberry for the last 15 minutes. Fourteen fucking years and she can't accept that time could be spent finding her keys. Makes me feel all stabby.

Also, unable to walk straight out of a shop door, have to pause . Get in car at garage and drive off straight away. Eat yogurt with eyes open. (Watch any ad for yogurt on the telly!)

No woman in history
has ever received the request for payment at the till with anything other than surprise. Men invariably have cash or card ready. Women look puzzled, then baffled, then start digging around in their handbags in the hope that there might be a purse there.

or even...
.... on the tube: tottering down the stairs in impractical click-clack shoes clearly unsuited to the act of walking at a velocity carefully calculated to cause maximum inconvenience to persons bringing up the rear; positioned at optimum coordinates on staircase to prevent overtaking by other people; conscious parts of the mind totally consumed with the vital task of texting her friend, before slowing to an even more annoying speed to engage in aforementioned bag-rummaging ritual to look for Oystercard whilst blocking the fucking ticket barrier.
Sheesh!

I'm glad its not just me
On a recent trip to London I purchased Oyster cards for the sole reason that Mrs. Captain Skippy didn't understand the old cards. She panicked every time we went through the barriers and scrambling for the card, couldn't understand which way round it had to go in the slot. Despite showing her repeatedly. It got to the point where when we went through the barriers I had to take her to one side to make sure she had the card ready and facing the right way.

I love her and all, but FFS.

This isn't a multi-tasking fail...
...this is an Advanced Planning fail. Most of the above examples are showing a lack of planning or thinking ahead.

I get fed up with female clients of mine who come out with that sexist BS about how "Men can't multi-task". I am a man and a very heavy multi-tasker. So I get female clients notice this and then say - "but you are a man, you can't multi-task". To which I just reply - "Well, as you're a woman, make me a cup of tea - Luv".

Why are women allowed to be sexist but us blokes get in trouble for it?
