I've only been through LHR 35 times so far this year. It will be 36 after tomorrow. Such idiocies as no towels in toilets, only hot air hand driers. For example, does it never occur to these idiots that people coming off a long flight might want to wash their faces? The annoyance in T5 of having to do a route march to get to lounges because they insist on having you pass over priced shops that you have no intention of buying anything from. The frequency with which lifts, escalators and moving walkways break down for several days, and the T5 lifts where only one out of the three is working at any one time. And of course, don't mention last winter's appalling lack of snow clearing...
All really down to the greed of a poor management
