Iced tea is generally regarded, in Britain, as almost incontrovertible proof of the existence of Satan. As a nation, we have greater faith in proper tea than we do in any particular god (or deity collective), however even tea has its demonic counterpart and it's iced tea.
Asking for iced tea may get you forcibly ejected from civilised establishments. In some counties, the legal punishment for unlicensed manufacture of iced tea include flogging, wedgies and, in extreme cases, collective tuttage.
The last hanging for public promotion of iced tea was as recent as 1951. A Members Bill is being brought to our lower house to reinstate the law and punishment. But that's the Tories for you. However, there are frequent news reports of people going missing after being found to be secret iced tea drinkers; this seems to be largely restricted to rural communities, fortunately.
For the most part, we are a liberal country. A broad church, some might say. As long as visitors to our verdant isle avoid consumption of iced tea in public and you are not caught encouraging others to participate in this perversion then you will probably be fine.
I shit you not…
