You could say that many vices are not typically available as part of a BA trip.

i) there is no casino or gaming area

ii) smoking cigars may come with a hefty fine

iii) carrying narcotics through airports and across international borders might involve a high degree of risk

iv) whilst ladies specialising in the entrapment of amorously inclined gentlemen can probably frequently be found on BA flights they are not, as far as I have seen, usually offering their services during the aviation experience.
