        While small may be beautiful, tall is just plain uncomfortable it seems, particularly when it comes to

staying in hotels and eating in restaurants.

        The Tall Persons Club Great Britain (TPCGB), which was formed six months ago to campaign(发起运动) for the needs of the tall, has turned its attention to hotels and restaurants.Beds that are too small,

shower heads that are too low, and restaurant tables with hardly any legroom all make life difficult for those of above average height, it says.

        But it is not just the extratall whose needs are not being met.The average height of the population

has been increasing yet the standard size of beds, doorways, and chairs has remained unchanged.

        “The bedding industry says a bed should be six inches larger than the person using it, so even a

kingsize bed at 6′6?′′(6 feet and 6 inches) is falling short for 25% of men while the standard 6′3′′ bed caters for(满足需要) less than half of the male(男性) population.” said TPCGB president Phil Heinricy,

“Sevenfoot beds would work fine.” 

        Similarly, restaurant tables can cause no end of problems.Small tables, which mean the longlegged

have to sit a foot or so away from them, are enough to make tall customers go elsewhere.

        Some have already taken note, however.At Queens Moat Houses' Caledonian Hotel in Edinburgh,

6′6′′ beds are now put in as standard after requests for longer beds from taller visitors,particularly

Americans.

D.They have to provide enough space for the longlegged.

4.What change has already been made in a hotel in Edinburgh?
