I took a London Black Cab recently and thought I would have a driver that would know the postcard sites and not demand a postcode to be typed into Google Maps on his phone. Since I was by now in a picky mood about the customer service aspect, I did wonder why this driver had no 'upsells'. So what 'upsells' would you have for the passenger in the back of a cab? Well, you can be on a trip to a meeting in posh clothes. Just having a mirror to see if you look the part could be most helpful in a cab, obviously a full length mirror isn't going to happen but something to check the spinach in your teeth might help. So there is a whole set of breath fresheners, mints, chewing gums and whatever else people need to get the spinach out of their teeth. Also, where can I get a latte in the back of a cab? Okay, maybe that is not going to happen, but a bottle of water can't be that hard to stock and keep chilled. What price an umbrella when you arrive with no coat expecting better weather? Then there are those that have not had breakfast yet. Cereal bars have shelf life, how much are they worth to late, starving people? A small pack of tissues, costs pennies but if you are late for that interview and need to blow your nose, would you pay £1 for those tissues? Cigarette lighters, maybe not booze and fags, but there is a whole cornucopia of every day stuff that the drunk crowd would want. I imagine there are good reasons why cab drivers do not offer these sorts of upsells (everything can be bought en-route), however, why do you need the products to be sponsored by brands and many millions of dollars of VC to sell a few candy bars and a few combs?
