One of the peculiar aspects of British people is that they do not know how to complain. They often just do not feel comfortable with it, even in the higher echelons of society.
How often have you eaten a mediocre, half-cooked meal in a restaurant, only to nod and smile when the waitress asks you if you enjoyed your meal? Not a word of complaint !
However those who work in professions such as publishing and journalism are beginning to get more vocal on the subject. They tend to eat out more often than other people, and they appreciate fine food and wine. They also have the fortune of being able to travel on a regular basis, and mainly in business class.
Apart from having the pleasure of doing something for a living which they usually love, they have the added perks on top! Wining and dining comes to them naturally, and they will often not hesitate to point out the faults in the quality of the food, the temperature of the wine, or the presentation, especially if it makes them look more knowledgeable.
I suspect though that for most people, complaining is only something that has to be done (or rather endured) if it is really necessary, and even then we tend to apologise for pointing out something that should have been done well in the first place.
