Business travellers get a lot of advice from company policies, guidebooks and websites. But some of it's so bonkers that it's funny -- and you should just ignore it.
From the people at the airport with those glad-wrapped suitcases, to that guy at the bureau de change who makes an obvious (and thus obviously futile) show of pulling his around-the-neck money belt, there's a whole industry built around pointless things or services that travellers don't really need.
We put our heads together in the Australian Business Traveller office and came up with our favourite (or least favourite) five pieces of commonly spouted travel advice that you can completely ignore.
1. Sanitise everything you touch
There's no need to be one of those crazy germophobes unless there's something wrong with your immune system, in which case you should probably be taking medical advice.
A special implement to touch the hotel remote control? Antibacterial disinfectant wipes stinking up the plane while wiping down the tray table like you're about to perform surgery on it? I think not.
Simple things like washing your hands on a regular basis, taking precautions where and what you eat, adding a multivitamin to your travel routine and practicing basic personal hygiene in crowds should keep you healthy.
2. Be paranoid about your hotel room
Ever read advice like refusing to take a hotel room if the desk staffer reads out your room number, or never putting the "please make up room" sign out?
If you're a business traveller staying in a business hotel, you're probably safer than you are in your own home. There's almost certainly no need to bring a rubber doorstop to jam under your door to stop intruders, and the idea that you should never let housekeeping into your room when you're not present is ridiculous.
Besides, making a scene at reception if your room number is read out? Good way to draw attention to yourself there.
Hotels aren't the dens of vice and thievery that travel advice-givers like to make them sound. Take the same precautions you do at home or travelling locally: keep your wits about you, look as if you know where you're going and don't flash obvious wealth around.
3. Buy those special travel toiletry decanters
You know, the ones that come in little white sets under 100ml. They're the daftest waste of money out there.
If you must decant your toiletries into carry-on acceptable sizes, just bring home some empty hotel toiletry bottles and refill them.
4. Bring your own special water bottle
I see business travellers doing this more in the US than elsewhere, but I'm still not convinced by the need for everyone to have their own personal hiking-style water bottle.
Buy a bottle of juice or water and then refill it if you're worried about running out of water between security and the plane. The hiking-type ones are just extra weight and they make you look like a bit of a tool.
5. Carry your own personal pillow
Whether it's those inflatable ones or an actual honest-to-God pillow, I do a double-take every time I see someone in business attire carrying them -- or, worse, suggesting that you pack a pillow in your bag.
I can't think of anything that looks more daft, or is a bigger waste of space in your limited luggage allowance.
