Although some people consider them-selves to be Christians, it's only the Christians who could be upset by inappropriate actions. Dilemmas like homosexuality, nudity, sex and profanity may be appropriate to the most of adults but a practicing Christian is going to be not simply ashamed but perhaps insulted much more than the typical person.
Hindu
Hinduism has a history of not eating meat because they see it as the un-necessary killing of a useful animal. Several Hindus eat a mainly vegetarian diet and will even avoid chicken, veal, lamb, fish, pork and dairy products.
Profanity and nudity are heavily censored in Hindu culture. They're less tolerant than the normal western community.
Generally speaking, it seems, food may be a bit of a hot potato which makes an impromptu business barbecue a little complicated.
