Riding cabs is the mode of the realm for travelers in any city not their own. Rental cars and trains and trams work, with more money or a bit of initiative, still, cabs are probably the cheapest means of purchasing mobility and possibly even scoring quick information about the local bests in eats, attractions, edification, and sundry merry-making.
Or not . . . depending on whose back seat you end up occupying.
Of course, it isn’t always a back seat. Since, in certain venues, custom dictates taking the shotgun seat. However, without a guidebook in hand (and then why pay for the cabbie for those choice informational tidbits?), it is not always clear which seat to take. It seems to me that once in Dresden when I took up the seat in the back of a cab, the driver did a double-take. Like: “who do you think I am, pal? Your chauffeur?”
Some people adopt the weirdest points of view.
