I’m partial sighted, pensioner on my own & can only see at 8” in front of my right eye, nothing from left eye so extremely restricted. Unable to see reg no.’s my supposed pick up point right outside Moorfields Eye Hospital reception in London to meet didn’t materialise. A member of public did kindly and eventually find taxi further up the City Road (A105) but I later found I was charged extra (with no agreement) for keeping driver waiting! and unanticipated central London charges that they know about! So much for fixed prices. Be warned. More worrying is reading reviews where drivers just leave without picking up clients and fee pocketed by online payment.
