As for my personal experience, during the summer and autumn of 1989 I waitressed for an agency in the City of London - director's dining rooms for lunch and then maybe a lucky banquet for the evening. These affairs were usually at one of the City Guilds livery halls or at the Guildhall itself. Doing silver service there was highly sought after and I soon found out that all you had to do was arrive at your jobs on time and not get drunk and the plum jobs were yours for the taking. Anyway, I cycled as usual in my black-and-white to the Guildhall one evening only to be told that I was doing top table (usually only done by chaps in butler's garb but they were missing one) and that Princess Margaret was guest of honour. From the amuse-bouche through to the savoury and desert she drank only scotch-and-water, lavishly topped up by her personal 'wine waiter' which we hoped would make her more amenable as dinner rprogressed. Alas it didn't. She barely grunted in answer to her neighbours - none of whom seemed to us to be in any way offensive or even bores - flicked the food around with disdain, smoked while others were still eating (between courses if you must but never during! - so my Grandmother says - fancies herself rather grand) and let me stand there with a buring silver flat on my arm while she refused to move over an inch so I wouldn't burn her shoulders (and I still have the burn scars on my wrist to show how long I stood there...) looked generally like someone had slapped her about the face with a large halibut - and worst of all, got up and swept out immediately after the toast to Her Majesty but before the others - like her hosts. I wasn't the only one who wished they'd done something to the soup. We were not surprised by such treatment as mere menials but we winced on behalf of the poor Company and her fellow guests. And I always thought the Royal Family - certainly since QV's time - had a maxim that to be rude, especially to servants - was beyond the pale. Mags was an exception there. Interestingly I did another one with Snowden some time later and he was wonderfully charming and gracious. Though I always thought his 'you look like a Jewish manicurist' jibe at her was beyond the beyonds too.
